My biology exam: "Describe the processes of transcription and translation"
Me: So hOtPoCkEtS...
all the comments from 5 years ago then there's me in 2020 tryna study this for my final tmrw
How did it go?
"Hey what's your WiFi password?"
"It's on the back of the router."
*Back of the router: **0:01*
God bless the editor who had to type that word for the video
+Jeannie Weasly Or, copied and pasted it from a website. :)
true, still that would be long copy and paste
+Jeannie Weasly It would take less than a second to copy and paste.
+lalaithan What about the guy who had to put it on the website in the first place? Poor chap.
+Dipper Pines Just a wild guess, but that person probably enjoys DNA-related topics or spreading knowledge and probably isn't bothered by typing.
Has anyone ever thought about this? This guy teaches in 14 minutes what a teacher takes 2 weeks to explain...
yeah but you kind of need a teacher to tell you this BEFORE watching crashcourse
Catia Park
It's all about how the brain takes in information. The majority of people need a slower, more in-depth explanation first, followed by quick reminders like this, if we assume that the current educational system is broadly on the right track, that is. If you just watched these without prior subject knowledge and then went for a test at A-level or degree level, you might not remember it all. However, if you have an unusual brain that is able to memorise every syllable of information crystal-clear, go for it.
... Well I can't do that, I usually just do some research and write about it n I'm fine 2 go 😜 (I'm not sure how long I'll remember it tho, depends on how interesting I find it!
ıts amazıng
my professor actually went through it as quickly as this guy except he didnt explain anything
the protein at the bottom of the screen gives me anxiety.
Tim Warner omg I'm not alone
Allah Akbar..
be careful or it will bomb on your face
How ironic that the fear of long words would itself trigger a fear of long words.
I have hippopotomonstroOOOOOOOOOOOOOOAAAAAAAAAAAAAAAAAAAAAAAHOHGODWHY
I WAS JUST ABOUT TO SAY THIS ,LIKE WHO WAS RESPONSIBLE FOR ALL THAT JFC
YES
On a test:
Question 14: What is the other name for Titin?
Hank talks pretty fast. So, I decided to play it at 0.5 speed to see how that goes. What resulted was the awesome discovery that Hank sounds totally hammered at half speed. Try it, you won't be disappointed.
I can't do this on my phone, but I can imagine it! Oh lord
+Bryan Sarauer i had to do it, Best. Thing. Ever. LOL
+Bryan Sarauer hahahahaha
+Bryan Sarauer LMAO
first 17 seconds in 0.5 made me burst out laughing thank you for that amazing discovery
And that was 2 weeks of school in 14 minutes.
Boy, I do love crash course.
crash course rulessssssssssssssssssssssssssssssss!
Sandhya Ganesan 2 weeks!?! We did that in one lesson, where do you live?
Sandhya Ganesan how old are you?
well, we did it in one lesson this week, but i made that comment two years ago so it took much longer then, as opposed to my current bio honors class
Yeah, one lesson for me too. came back to this video so I can understand it better and I think I'm finally getting it after 5 attempts xD
Imagine how chaotically beautiful medicine would be if everyone had the naming sense of the dude who named Snurps and Spliceosome
poor scientist who had to write down the name of titin
+Viking Arhold wouldn't they have chosen to make it that long
Don't worry, he just used a random number generator to make it ;)
+gameturbo131 don't you mean random letter generator? lol ;)
Fadel That makes sense XD why else would you have a pointlessly long name?
yeah +gameturbo131 lol unless you are talking about supercalifragilisticexpialidocious
Nobody:
Poly-A tails be like: *_AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA_*
Yes, there are 250 of them
whoever took the time to write down that protein at the bottom of the screen - I commend you for the time and effort you put into that
unless they just copy/pasted...
altie29 Someone had to write it down first; the original person who bothered to write down Titin on the internet.
Hendrik Henderson Who the hell named it really -__-
mikotorubychan It's incredibly long name is actually not a result of a bored scientist; Titin happens to be an IMMENSELY long protein strand, and there is a certain scientific formula for naming proteins. Most proteins have long names, but Titin's unusual length makes it have a longer name than usual.
I think they copied and pasted
me, a senior in a biomedical degree, needed some hank green to resimplify transcription and translation after my professor made it unbelievably complicated. thanks hank for making me feel sane

Thank you so much my guy.
Im convinced the editor just wrote random letters after the first 10 seconds
"sorry for all the terminology"
NO! For gods sake man, I have a midterm in two days. More terminology. Save us Obi-Hank, you're our only hope
XD
lmao :D
guys
This entire thing is INSANE
Don't you guys think this shit is MIND BLOWING? this shit is happening in EVERY SINGLE ONE OF YOUR CELLS
How do they? Who.. Who told them to do this? WHy do they do this?? WHAT
+mickeynotmouse JESUS
+mickeynotmouse God
Brain
the brain is just made up of MORE CELLS DUDE WHAT DO YOU MEAN BRAIN
+mickeynotmouse They move and assemble via the random movement of tiny particles on their size-scale (because they're so small they're moved about by the tiniest force, absolutely everywhere, very fast and jittery) and behave according to a force of entropy (a natural force, like gravity), using up the free energy around them until they form a stable molecule. Because of the shape of some molecules, like the base pairs and amino acids, they'll only arrange in certain ways with the opposite molecule that fits them, or into an optimal (best) position/energy state. Some physics comes into the biology of understanding how the particles behave... but as to how they became this way, the most well-reasoned explaination is evolution and mutation.
At the beginning of life, the theory (short version) is that chemical particles reacted to form amino acids which formed proteins that lead to the first RNA, but the evolution of cells and and how they developed these complex processes needs... a bit of a stretch of imagination.
"All of those hydrogen bonds cause wrinkled sheets. UHUH!"
XD Hank, that had me weak! 10/10.
who else has a final tomorrow and didn't study?
+mimi goddest me
Why would you not study..
I got a project and have no idea what im presenting 😧
Midterm but you get the point
Bruh... me
God bless this guy. I don't think I'd be passing honors bio with out him 🙏🏼
He was blessed by the lord FSM.
+yasmine abdouni SAME I'D FAIL HARDER THAN I ALREADY DO
+yasmine abdouni i still am not... lol hopless
+yasmine abdouni Using him for some last minute ap bio, for a bit of basic review.
"What are you going to name the Splice thing, professor?"
"The... Ummm.... Uhhhh.... Splice... osome? Spliceosome???? I guess???"
Okay but snurps though 😂 finally a science word I can remember!!!
How do u eat DNA spaghetti ????

Crash course makes A level biology much more understandable and fun!
He's better than my teacher tbh
you look pretty
...
the thirst is strong in this one
Yaaaaas... Oh I hate paper 4
Exactly, in 14 Minutes he's done more than I've learned in 14 days...
Well you have to go home and study on your own. Your teacher can't hammer it into your head in 1 hour this stuff is complicated.
boost
newyorks516 well hank lightly tapped it all in our heads in just over 14 minuets.
This video should serve as no more than a review or reinforcement to material you have already studied and learned on your own, from a textbook. Unless you are not majoring in biology or any of the sciences ( and you think this will suffice for exams) I recommend you do more than watch a 14 minute video on such complex concepts.
newyorks516 dude I'm a freshmen in high school, plus I want to go into psychology.
Hank Green is saving my Biology A Level one video at a time.
if this aint me then idk what is
can i say how true this is
I saw a typo in the full word for titin. I demand for it to be fixed.
Fire the editor!
I will find that word and dedicate my life to memorizing it
Captain Lightbulb why
because he is captain lightbulb
Basil Almasri dont act cute
xStussGeo don't tell them what to do >:[
It's been three months, memorize it yet?
Have you ever wondered why the DNA contains thymine, while the RNA contains uracil? Here's an interesting fact. A spontaneous process called deamination (replacement of amino fuctional groups with keto groups) is fairly common in both DNA and RNA. As it happens, the product of deamination of cytosine is uracyl, and it is the most common of deamination processes affecting the DNA. The product of cytosine deamination (uracil) is readily recognized as foreign in DNA and is removed by a repair system. If DNA normally contained uracil, recognition of uracils resulting from deamination of cytosine would be more difficult and that would in the long run lead to a decrease in GC base pairs and an increase in AU base pairs in the DNA of all cells. Establishing thymine as one of the four bases in DNA may have been one of the crucial turning points in evolution, making the long-term storage of genetic information possible. (Source: Lehninger Principles of Biochemistry)
Also, we commonly speak about introns as the junk which gets spliced leaving the ''important'' stuff for translation. Why do organisms have introns at all? It has been shown that introns are responsible for boosting expression levels of proteins up to 400(!) times (parts of DNA coding for introns include regulatory elements involved in transcription), they contribute to DNA packaging (chromatin formation), control the delay between gene activation and appearence of its protein product (which is especially important in developmental processes) and are responsible for alternative splicing. This latter process is extremely important because it allows one gene to produce multiple proteins, thereby increasing complexity of organisms without the need for occurrence of thousands of new genes. Also, many non-coding RNAs are actually products of spliced introns, such as miRNA, snoRNA, lncRNA, siRNA... (Source: www.ncbi.nlm.nih.gov/pmc/articles/PMC3325483/)
thanks
there honestly needs to be teachers like you because teachers who cant teach but are there cause that the only job they can have need to stop.......
my bio teacher lol
Raul Pinto or anthropology teacher!
I'm studying for the AP Bio 2020 test on Monday the 18th, so the Crash Course intro is now my personal theme song XD
Also, for anyone studying (or cramming) for the AP Exam:
Things are different. Things are /hard/. We've struggled all year, clawing and biting our way through the piles and piles of knowledge that class has thrown at us. But this just proves how freakin' STRONG we are! Look at all we've come through! For what feels like forever, we sleep, eat, and breathe SCIENCE. And it's gonna pay off. I promise. WE CAN DO THIS!!!!!!!!!! On Monday, we're gonna put on our comfiest clothes, grab some coffee/tea, log onto that computer, and show this world just how awesome we are!!! You might be feeling a little powerless in the face of new changes - or even in the face of the all-too-familiar enemy of self-doubt. But once you realize that there's no punishment for failure and only reward for success - that's power. Once you realize how /prepared/ and /intelligent/ you are just for making it this far already, /that's/ power. You've got this. Trust yourself to do amazing on this, and I promise you, you'll come out on top.
my friend, the time has come, let's all pass this test!
@@red-pe1ue YES!!! Good luck and keep that positivity going strong! :)

Just wanted to point out two minor "mistakes" in the video at the 9 minute mark.
1. The first tRNA should be in the middle side of the ribosome ("site P"), THEN the second tRNA will go in the right side ("site A")
2. The ribosome should be the one "moving" during the animation, not the mRNA
Anyway, awesome 14 min explanation!
+Ciize09 thank you
highered.mheducation.com/sites/0072943696/student_view0/chapter3/animation__how_translation_works.html
These videos are a part of my homeschool biology curriculum. Great work Hank!
Also ham and cheese Hot Pockets are my favorite as well.
"YOU NEED TO KNOW IT" lol died laughing
Today I had a lecture by a lecturer who studies proteins. When he asked us to give examples of proteins, I gave Titin as an example. He was like "OK...that's a protein, apparently."
Longest protein in the world and he doesn't know about it, despite studying proteins...what?
Strange.
+Abominatrix650 In his defense. The books he studied aren't long enough to fit Titin in them.
+Josh Marks HANK SPECIFICALLY SAID "WITH TWO 'I' ". HOW COULD YOU????? Titin*
what is longer, our DNA strands or 'Titin'
it's also known as Connectin, so he may know the other name
an 80000 letter word?
ain't nobody got time for that...
ikr
guitarhero5437 Except the guy who wrote the entire thing in the video. I feel sorry for that man...
Aysia Milaan Lol u got top comment on this vid too?
Aysia Milaan Try 189,000+!
All the comments from 5-7 years ago and here I am in 2022 studying for my midterm thank you crash course
Wow, great video. Only like ten percent of it stuck, possibly less but it's still a good video.
Same lol
thank you for making biology relatable and understandable!!!
I failed my test because I spent two hours looking up and creating a hot pocket rather than studying for my bio test....
This taught me, in 11 minutes, what an entire chapter in my entire textbook's failed to. Thanks for such an amazing content!
Macro-evolution truly is insane. The fact that a bunch of subatomic particles can create intelligence from only wanting to bind with each other. And then the intelligence is capable of seeing and studying these particles! Amazing.
Jack Pistone...So. You just made up your own idea of what evolution is. Then called that idea insane. Nice strawman there sir. Very nice indeed.
Dave Robson it's actually thing. In sombre circles there is a debate between whether or not evolution exists or if it is exclusively on the microscopic level.
Both micro and macro evolution exist, they can't exist without each other. I understand you were being sarcastic but I say really look into evolution. It is truly amazing, even if a little insane
college senior...still needs crash course xD
I would not have passed AP Biology without these videos
Amanda Watson wait that’s an actual thing
Is no one going to talk about 2:34 - 2:38? lmao
+Mihir P Hilarious, he does it again at 12:36
lmao from this titin down here
put tht to 0.25 speed
lol
Hahaha, wow I actually didn't notice his face the first time, I was paying to much attention to the word itself.
These videos are more helpful than any office hours session I've ever attended for any college science class
-struggling nursing student
I love the way he explains: easy and, at the same time, deep on the topic. Thank you very much for the classes. The edition and animations are GREAT too!
they should have these vids be required watching in school
They are at my school it's homework
that's awesome
My biology teacher shows us these, and I got addicted to this channel.
that's amazing...good luck studying
in my class we get tested on this she asks us what video we watched and then it has to be crash course bozeman or something and she asks what he compared it to and everything
This video taught me more in 15 minutes than my biology teacher ever explains in a week. Basically this video alone got me a 90 on the test to thank you Hank!
LOVE Crash Course! You guys perfectly condense a really complex and complicated subject into like 15 minutes and present it in a way that is super easy to grasp. Y'all are my HEROES!
When crash course gets you a better grade on finals than your acctual teacher 😩
This is what i am naming my first born child. Just to bother his teachers when they introduce him. ("This is..." *Five hours later...* "Say hello class!" Am I evil?
Dangit. I cant ruin my future childs life just by naming him... ARRGGhhh
but i want to be mean! Titin isn't long enough! :P
Titin's cool.
Names don't have to mean anything or make sense. Make up a name that's easy to pronounce, but takes about 15 minutes to say.
zemorph42 So just make the name aaaaaaaaaaaaaaaaaaahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Why didn't I discover these videos sooner, I could have done better on my exams :(
"So grab a hot pocket"
Me, sitting on the couch with a hot pocket: way ahead of ya buddo
I watched a ton of central dogma related videos to wrap my head around translation but this was the only video that truly answered some burning questions for me as well as gave me some more information on protein structures in a hilariously entertaining manner. Good stuff man good stuff.
Explained it better in 14(ish)minutes than my Bio teacher could in a week!
"Hank Green: Better than a Hot-Pocket"
Uhh, what did you do to hank???
Andy young He says he's better than a Hot Pocket toward the end of the video. I think it makes a great slogan.
Maeghi Miércoles ohh ok I thought u ate him XD
lol XD it really is an amazing slogan..
Hank is my new favorite person.
same for bio
Easiest way to remember the START codon for translation: school starts in August "AUG". The movement along the ribosome, the "E" site: exit site, "P" site: polypeptide chain site, and "A" site is the amino acid site. I hope that helps with remembering some information during translation!
thanks for helping me through 1st year bio x
This video is so helpful!! I learned so much more in this video than I did in 2 biology classes- Thank you Hank!
Rewatching these for studying :D though sadly I need to know more than what Hank has presented lol~ solid refresher tho ^^
I feel you.
AP exam tomorrow. Here goes nothing
+Nakolas Lol same
Stop enabling me
what did you all get?
what does AP mean?
don't worry about it, you're not smart enough. lol
Hank Green; better than a hot-pocket.
Thanks so much for these awesome videos! I get so bogged down in the details and these really help me to get back to the "big picture" :)
Thank you CrashCourse team!! Your content is of such great quality. Have been watching this so many times, first for my biology classes in high school and now at university for quick revision. Honestly you must have gained so many good karma points for making these videos!! Wishing you all the best from the Netherlands.
Hank has a tick that I cannot unsee... he constantly bumps his glasses up on his nose with his finger.... 2:18
sorry, more like 2:13
+Kevin Klika it might just be that his glasses are not well fitted so he needs to readjust them frequently
+Kevin Klika He could potentially consider contacts or lasik after reading your comment. :P Interesting that you noticed, btw. My brain is overloaded simply by trying to follow the biology. He speaks fast, but I like it.
+Kevin Klika I assure you everyone who wears glasses does that
The Great Danku Tree I wear glasses, and I understand readjusting them, but the way he hits them with his finger (and puts a big smudge on the lens) is more what my comment was about...
I really enjoy your videos. I went from a C in lecture to a B within a matter of a few weeks after finding Crash Course. Thank you Hank for being awesome and funny.
Who else is watching this 20 minutes before their honors bio exam?
me
Katie McCloskey Yeah
How the heck did you know it was honors?? Lol
Did you make it?
Dang that's me right here and right now
7 years later and this still helps me with school … amazing! Your videos truly transcend time!
Keep up the great work!
Yes, Hank, I think we'd all agree that you are better than a hot pocket
These videos are extremely helpful. I find that the animation really helps to visualize genetic concepts that are hard to figure out from diagrams alone. Thanks Hank!
I can not thank you enough for this, as well as your other videos. You make learning college biology fun and actually understandable!
Tavia Hedrick I’m learning this in my freshman year :/
You just gave me more information in 14 minutes then my lecture teacher gives me in 5 hours and it was easier to understand... Thanks :)
I love all of these they are SO FREAKING HELPFUL WITH THE EXPLANATIONS and table of contents. Thank you so much
he is the reason I pass my biology tests. After j watch his videos I go through my notes again, and then they make sense.
Also I have a good biology teacher but having it all compacted and visual is a blessing.
My mom "What are you doing waching videos, you need to study for biolo... Oh you are. My bad" me:" L0L"
A BIG THANK YOU FROM GERMANY! You really helped me getting through my exams with the funny and informative way of teaching these complexe topics!
Without your videos studying really sucks... :)
I don't think that I can express my appreciation for these videos. Crash course biology is the only thing getting me through AP biology. Hank green, you are my hero.
Thanks thanks thanks soo much these series help me understand what I'm learning in the classroom much better. I can see all the dedication and hard work that's behind these videos and they come out beautifully. I always enjoy learning with you, awesome work!
College Biology Exam tomorrow. You just saved my grade!
So, did he?
Yep!
What was your grade?
soul star ssama 92%
I have a test tomorrow on this subject, you helped me very much!
Hi Hank--my students and I love your videos. Have you every considered doing a short series on the discoveries that led up to these concepts, especially all of the molecular biology? I know some things, and have been able to research others, but would love to have it all collected in one place! Then I wouldn't so often be stumped by questions like "how do they know that DNA polymerase is the enzyme that connects the Okazaki fragements" and "how do they know ribosomes have 2 sub-units" and "how did they figure out which codon codes for which amino acid"? (you can see I have students that prefer not to take things on faith!!).
I have a bio test over this tomorrow and I've missed so much school when we were learning it you're literally my life saver
I can make the word go in whatever direction I want it to go, if I want it to go right, it goes right and vice versa. Try it and amaze yourself.
This is amazing, i'm mechanical engineer (not english native speaker) and i'm understanding everything in this series of videos; the nature is amazing, how through evolution it has created this enormous machinery that can store and use information to make and incredibly complex machine like multicelular living beings!
"evolution......created.... machinery....information... complex machine....". since evolution is the antithesis of creation, this sentence would make sense if "God" was substituted for "evolution". It seems you are demonstrating the accuracy of Romans 1:20, Abraham "For since the creation of the world God’s invisible qualities-his eternal power and divine nature-have been clearly seen, being understood from what has been made, so that people are without excuse." Clearly you know machines are "created" - so why not acknowledge the Creator?
Debbie Eberle-Sherman well with that same logic if something incredibly complex must be created then who created God? And who created the creator of God?
Kyle a The concept of 'God' is an intelligent being that does not have a creator. What effect this has on your beliefs I'm not really sure. Also, there is such a thing as 'God-guided evolution'--the belief that a deity controlled evolution's path. Then again, it's up to you whether you think it's right or not. I'll be waiting here with popcorn, a Swiss flag and the WWE championship belt.
On an unrelated note, hot pockets are yummy.
On another unrelated note, some Chinese dude managed to memorize >140,000 digits of pi. Who knows what he could do with that protein?
***** YES. That's the sort of person we need.
Elizaveta Hedervary my atheism is being shaken by this, as well as several other elements of science.
I've heard Richard Dawkins hypothesised this complex life might have originally come from, basically, ETs, seeding this planet. Intentionally, or accidentally. I wouldn't have expected that kind of theory to come from someone like him, although it seems vaguely plausible to me.
Can someone please explain to me what other 'best guesses' the atheist camp have for how we could possibly have evolved a genetic code, billions of characters long that contains information to create amino acids in the exact right combination for them to actually make functional proteins? I think Steven Myer said the chance of a typical 150 amino acid long protein was 10 to the 164th power.
So chance is out, natural selection couldn't account for this complexity existing from the first cell, so what do we have?
Again, I was brought up an atheist, I'm not looking at science and trying to make it fit my existing religious beliefs, I don't have any, but seriously, this looks exactly like a computer code, and those surely don't come about by chance, natural law, or any combination of the two.
I swear to god these crash course videos are more valuable than both my high school and college educations combined
Thank you so much for making all of your videos, theyre so very helpful!
ive been watching this video for hours LITERALLY!! Finally got a bit of it iN ma head ..phew thnx :P
Hank is left-handed YES!!!!
Crash course helped me pass my psychology class in college, now I'm back for biology, so thank you for all that you do.
These videos literally save my bio grade. Like I don't know what I would do without them. Thank you for being a better bio teacher than my actual bio teacher.
Who else watching in quarantine?
You just saved me for my biology exam on Thursday. Holy crap.
Thanks for all your help Hank, Love the fun way you explain it all!
Hank, everyone i know at sixth form loves you, keep going buddy!
Watch me pass my biology final exam (i'll come back)
Someone should make a nerdrock parody band called AT/GC
...anyone?
That would be super awesome!
Thurgor Supreme With their hit song "DNA (Oi!)"
This channel is insanely good at getting the point across with minimal confusion. Hank speaks at 200% the speed of a teacher yet he is 1000% more understandable.
Thank you so much! i have no idea what i would do without crash course! It makes biology understandable and easy.
