The DNA in just one of your cells gets damaged tens of thousands of times per day. Because DNA provides the blueprint for the proteins your cells need to function, this damage can cause serious issues-including cancer. Fortunately, your cells have ways of fixing most of these problems, most of the time. Monica Menesini details the processes of DNA damage and repair.
Lesson by Monica Menesini, animation by FOX Animation Domination High-Def.
If I ever meet people who'd peer pressure me into doing things like smoking, I'll just remember the little guys in me doing their job. I don't want them to struggle, it's hard work
Oh! That's so kind of you...
it happens only for a certain limit .you cant expect your body to go back to normal after smoking for 5 6 years .
They will always struggle because of the sun.
☝
Me too hahahahaha
My body is smarter than I are.
*My body is smarter than I am.
Now get back to work! >:D
+Alin Marginean definitely
rajasakthiyan maniji If a cell is smarter than us, then a "body" of cells must be smarter than just a single one.
But just think. You are your body. Your brain is part of your body. Oh wow shit just got deeper
Apparently not if your fingers typed in the wrong words for that sentence.
I never realized just how complicated the insides of my cells were until TH-cam videos like this.
Ahhhh I c u in almost every TEDED video
+Shawn Ravenfire Didn't you take biology back in High School??
Harold Martinez Yeah, a really long time ago. If I learned any of this, I probably forgot.
this is why it takes 5 long years to go through medical school. So much intricacies
Don't take a mRNA jab! Its not a vaccine. Its a experimental gene therapy. Know your rights in this case! Check the Nuremberg codes that ensure your legal rights to refuse to partake in this experimental jab. Science cases have showed that mRNA has killed animals during tests after a while. At first they looked completely healthy. After a while they got sick. There immune systems responded dramatically. This caused massive flue deadly flue symptoms. These were long term effects! Don't let your body be told how to repair itself by an external flued! This damages the natural repair process! Stop believing all the deception! Its your body and only you will suffer the consequences! Its a trick and you allow yourself to be fooled by the media, government and pharmaceutical industry :(
It is wonderful how much work and effort our body takes to keep us alive.
+Willan Gaspar Yes good point!! It's amazing!!
+Willian Gaspar Its all just a chemical reaction
Thanks for thinking like me :D
but still How does the body cells control which reaction should happen
AlphaMineron Through more chemicals hahaha
urm u meamt how much work we do to keep our body safe
Our bodies are amazing
+FrozenEternity thank you
I think our god that created us with such an amazing way is more amazing ;)
(To Mayta) "I think our god that created us with such an amazing way is more amazing." With all due respect, isn't there more evidence to support the following statement?
Our creator allows suffering and possibly delights in it.
yes you are right
Satou Tatsuhiro Satou Tatsuhiro, you're acting like a bully. If you have constructive information, then share it. If not, no need to spread hate, so don't bother commenting.
these cells and proteins are so adorable i wish they were like that irl😂
I would you know what they are like in real life. If you never seen them.
Earl Fechter LOL
Well that'd be a lot of work, you see.
@Earl Fechter and very deadly
@Earl Fechter You need help🤣🤣🤣
Episodes like these beg the question: HOW THE HECK DO THEY FIGURE OUT ALL THIS STUFF?!?
+Squid Larry A good scientist with a good microscope and good timing most of the time.
+Squid Larry Decades of studying?
I know, it's just really amazing.
Squid Larry Yes, it is :D
+Detective Shaft Yes that, but multiplied by *generations*. Each scientist standing on the shoulders of the giants that came before them, further adding to the knowledge discovered by their scientific predecessors, so that someone in the future may stand on their shoulders too and continue the work. The generations go by, each taking another further stab at the immortal beast that we call Ignorance, it gets constantly weaker but it will never truly die.
I got goosebumps. People really need to respect their own health. I'm soo proud of these tiny doctors.
True
if only i have youtube back in my school days. i will be one of the smartest chaps on class
+Eko ari wibowo no.
Vic why not?
+Eko ari wibowo these aren't really relevant to the school syllabus and r usually for general knowledge
i watch youtube video everyday and yet i still cannot get a good grade
Sidney Tan you never watch khan academy? its very relevant
Man, this incredibly fascinating. I never knew how intricate and thorough this system was. Neat!
Assome!!!
Yep
Every Person is A Hardworking 😎🙌 But. From Inside The Body. 😅

@@YouSuprised I would recommend taking an introduction to immunology lesson before making misleading, and irrational comments~ It might harm people without prior knowledge to biomedicine😊
I like how the specific enzyme enters wearing shades to let everyone know its important 😂
TheSlimmshadyy 02:19 lmaoo,,
YES😆🙂!!!!!!!!!!!!!!!!!
Like the managers or boss of a company lolol
This is FBI! Move or be moved!
"stand aside civilians"
Microbiology and Cell Science student, here! This video is an absolutely AWESOME introduction for anyone curious about DNA repair pathways used in human bodies and in microbes! I hope this inspires young students to become future molecular geneticists. Thank you for this video!!
I hope so. But I think the actual process of finding all this won't be as fun n interesting as this video!
Med student here I can confirm. If only uni was this pedagogical :(
I sure wish they would have said what lifestyle choices we could make to give our bodies the necessary resources to facilitate repairs at Peak efficiency. You're probably done being a student now so congratulations on that. Please let us know if you happen to have an answer to my above question.
SOS Repair
4:11 The worker cell's like, "Hey man, it's 5pm, I've gotta get over to the endocrine system to fix another batch of these."
Foreman cell: "If I lose my job, I'm blaming you two."
Lol
I just wanna take this moment to congratulate the animator on making the enzymes so adorable.
This animation is so cute :3
ikr! I was all like aww my enzymes are so cute, lol
Nice peridot pfp

Nice.
🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
Wow... they could make a whole game out of the animations and concepts shown!
Facts kmlol
Cells are AMAZING
But we kill them with xrays 😕😕

During the video I looked at my hands and were like ''What the fuck.''
I love how the enzymes are working in teams and actually get things done. When we do group assignments, either one of us would do the whole thing and we all get credits for that or none of us does anything and we all fail.
Those scientists who have discovered these processes really deserved their Nobel Prizes. Such a fundamental process of maintaining life. Amazing biology!
It is amazing to see how everything fits so perfectly. From tiny molecules to DNA, to cells to tissues and muscles to multiple species to an ecosystem to environment ! Then Science and Mathematics. How this universe is so perfect, having solutions for problems.
@@mikem4481 which God
yes my friend, because Jesus our author loved us this much. He loves you too, check out his story in the Gospel of John. God bless

DNA so smart :)
DNA is* so smart. :)
+Karmifia DNA... so smart :)
But then the body gives up at life when the telomeres run out. There are ways to trick them into restoring telomeres, it's good most of the time but cancer, so there is already something to solve that most of the time.
The the enzymes are
+Karmifia hahaha
It's incredible and the animation is sooo adorable :D I better take care of my body better to keep these adorable lil things happy :D
I guess u still look digusting after 5 year
Why don't schools teach in such way?
School sucks
Because except for learning in a simple way what is happening you also have to know the exact way it happens and that can be kind of boring
Its detailed but the teaching is boring
Because it's useless. It might all be a lie, and what prsctical purpose does this knowledge serve anyway.
I mean videos like this take sooo many hours to make
we need this instead of teachers
trueXD
This _will_ be the teacher
the people who made this video are teachers.
So far my favorite animation from TED-Ed!! It really does make it look like everyday-life workers and mimics how complicated it is.
Only if we were thought biology like this.....

Tight
And English
@@prism2451 😂
My body always amazes me to no end. Great video Ted!
This is more amazing than I imagined it would be
Wonderfully explained. Kudos to the team behind it. ❤️
absolutely incredible. how these processes found is another incredible story.
Wow! Im completely amazed.
I didn't know how busy my repair and support teams are working that good.
This video just covered my whole exam 2, which was about 5 chapters in my genetics textbook 😮
Oh really
Why is a 6th grader aka me, watching this then? 😂😆
What were you studying
The animation is amazing!
This is very incredible with proper elucidated explanation.
Explains in such a simple and interesting way. Very good one for recommending students too.
Hi John, your videos constantly inspire me to think and discover and learn. Today I was inspired to learn about my own state's state insect: coccinella novemnotata or the nine-spotted lady bug. This bug is in fact native to NYS; more broadly it is native to the US and to southern Canada. The lady bug is extremely rare, in fact the last known spotting of this insect in NYS was in 2013 on a farm in Long Island. There was a proposed bill to replace the state's insect in 2006 but it was not passed. I, for one, hope this bill is not passed and I hope somehow, someday this ladybug will find its way back into New York State.
wish humans will become collaborative like their cells and stop fighting.
billion dollar comment....
Wow, I like your thought. Hope for it!
Too much diversity destroys humanity just like it destroys cells.
These are molecules not cells
When a human dies, it's not that their cells die, it's they they stop working together.
the fabric of intelligence this world is made of keeps me in such awe knowing that we are loved beyond what we can comprehend.

What a wonderful lesson. I will share it to all my clients for better understanding of our bodies resourcefulness.
Anyone else think they have cancer now
+Covalent Bond no
+Kristers-Raivo Krams He's like me, we worry about a lot of things
Majority of mutations are silent mutations. It's 'difficult' to get the right mutation to lead to a malignant tumor. That once cell would also have a lot of battles agains the rest of our body's immune system. He will first have to reign supremacy against our immune system before battling US. which I think is quite difficult to do.
But, if your genetic family has a history of cancers it will make it easier for them because it'll indicate somewhere in your genome is a coding for something that is less than 'fit'. And even then it's still difficult.
we already all have cancer, cells that have a wrong dna structure are cancerous cells.

Great job on your animations, by just listening alone this may seem really complicated to imagine but with the help of videos, I can easily understand. By the way how many medical videos do you have in total?
Amazeballs. And knowing that it's completely non-sentient and completely mechanical (ie. clockwork) makes it even more amazing.
Oh thank you so much for this awesome video. Did NOT expect this level of clarity. Much love, S
Wow. I would have never guessed that my body is doing this billions of times a day for me to go out in the sun and get severe damage ...I’ll be taking care of my body more.
I am fearfully and wonderfully created.
I learnt this in school but these animations are spot on!
This is the one of my favorite video from TED ED.. THANK YOU ted ed for the knowledge.. keep it up..
How wonderful is the way our bodies work . Such sophisticated processes keep us alive however at times we all blame our genes for slight defects in our looks and abilities. We must appreciate life , an amazing existence ❤
I sometimes just can't figure out how these small things in cell, are so specialised in doing something and making decisions to things sometimes they even aren't "trained" yet. Do they have some sort of "brains"? Or are they just some predetermined sets of procedures ready to be followed? If so, how do they know what procedure to follow next? Maybe, due to some chemical reactions that drive these sets of procedures further. But who in the first place put those steps? Evolution? DNA? How do these things know what's best to adapt to environment and live while still being an "insignificant" stuff that can't even think? Isn't this amazing? But I think of it more as a mystery yet to be unfolded...
that's what the DNA is for so they don't have to be trained to know what they are suppose to do, Think of it as babies they know if they scream or cry it causes a reaction In the parents to feed them or pay attention to them.
Now u are deep thinking, and thats what we don't want you to do. Coz then you will become religious and start missing days of work to go worshipping..
@@banurarich3854 Well there's nothing wrong in being religious first of all, second you need to think deep to be good at science. If you just take other's scientific observations and conclusions at face value without trying to think about them, you will learn nothing. And, this was posted by me when I was in grade 10 lol. It was only these sorts of questions that motivated me to study these phenomenons further. Now I can say I have a decent understanding of it all.
You are amazing. Could you share a bit of what you learnt?
I have watched this like 4 times, I haven't learned much but his voice has calmed me so much I'm ready to fail this exam like a boss.
As a person who's specialised in DNA study, this video is very accurate, interesting and informative. For an undergraduate who studies DNA Repair this already covers a lot of important ideas.
Thats pretty incredible
hi, the DNA illustrations here are incorrect. in the video it is shown as a pair of parallel polynucleotide strands while it's supposed to be antiparallel, which means parallel but run to the opposite directions :)
Why does this feels so calming 😳
I usually never comment on things, but this animation right here deserves gold.
If only I worked half as systematic and as hardworking as my DNA repair guys inside my body ..... my life would've been much better :)
0:18 !THATS A LOT OF DAMAGE!
This is the reason why I have a microbiology major this stuff is fascinating.
AMAZING.... Simplicity is the key!
Next TED-Ed: how to repair DNA by meditation via neuroplasticity and extending telomeres
Jeeze, didn’t realize enzymes could be so smart or organized.
Amazing. Thanks for this video. Incredible way of natural repair.
Love the way this channel illustrate this concept.
how great! our body is a living miracle.
while good info, and cute animations - it is too bad the DNA is drawn backwards ... (A right handed turn is correct.) Avoiding damage is a good way to reduce risks, too! Look into dynamic genomic integrity, and make some easy choices... (and push for less toxic ingredients too!)
Nerd
@@kspnightlynews3283 LOL
That was so simple and fun to watch!
This is so well done. THANK-YOU ❤️
My cell is more hardworking than me...
No cap, same here
how do they recognize an error?
+Muhammad Yahia Tarabishy That depends on the type of error. Different systems (aka proteins equipped to handle the situation) have evolved, to react to each source of damage. Basically, most errors that can occur disrupt the DNAs helix structure and the repair systems can identify these flaws.
+Manuel Reisinger if our enzymes can recognize error in our cell. why most of the time they can't recognize virus RNA while replicating?
Because viral DNA doesn't look different from ours. Its the same building blocks, so there is no change in the helix structure that the DNA repair systems could recognize. Its not their job, that's what the immune system is for =P
+amine err No.
+amine err Was not supposed to be.
This was so beautifully made.
I am an examinee who will take the CSAT in Republic of Korea. In the Korean language area, 'dna damage recovery' is in the test range, but I had difficulty understanding this content because I only took physics and geoscience. However, this video was very helpful in understanding the contents. I heartily thank you.
i didnt understand a shit but whatever our bodies are great
Lol me too
how do they know this?
God
+Jake Simmons Satan make cells so human can live longer and cause more sins.
+253637zero2 that. makes. so. much. sense. its all clear now :)
+Troy Milton Watson & Crick.
Enzyme based assays...
omg, u have no idea of how u have helped me with my assignment. Thank you so much and keep it up.
I just loved the last phrase about "The Fountain Of Youth"
Amazing how advanced this is. Yet people say there's no God
+You Can't Stop Us Christians I can't understand it either. It must be magic.
Lugh Summerson Magic and sorcery is satanic 😷
You Can't Stop Us Christians
Bronze age superstitions? Do tell me more...
according to Christianity logic, things that are complicated or hard to understand are either demons or God.
+You Can't Stop Us Christians You can continue watching more Ted videos like this for explanation of why there may be no God. This is science, go deeper.
Lmao those enzymes are so kawaii.
I am always so impressed by the resources which explain biological processes so simply. I could have struggled with papers published in pubmed and it would have taken me hours to understand the information presented in this video.
We need more animation and explanation like this.
That voice...
its so boring i
Alexa, play DNA by BTS
I'm listening right now while watching this video
This video is awesome, makes it so much easier to understand ! It's almost literally the same as in my books on radiation treatments, it's very accurate but also very simplified ! Thanks !
What a brilliant demonstration of DNA repair!
why isn't any one giving credits to the true master mind behind all this ....God the one who designed and created this body.....
Because not everyone believes in him, simple
@@pinnacaridpeep2889 well ... your missing out on soo much...
I might should stop eating so unhealthy :D
im alergic to cow milk, salt, sugar, and white powder and the alergy was from my birth :D
Ouch (o_o)
Im sorry 4 you
+Ace Wayne its okay haha
Ace Wayne its not a joke by the way all my friends say how are u still alive i say easy life a life haha
I live how i live and i get away from it very easy like at school i know what to eat and they give us healthy food haha its okay
I really liked the animation of this episode. The images were appealing, but did not take away a confuse any of the concepts.
so beautiful animation i have watched for the first time about DNA
SubhanAllah! All praise to Allah
i am first so plz stop saying first
ted ed always leaves a smile on my face!
Informative and brilliantly animated.
So much shit to keep you alive and even then some people commit sucide because of stupid human reasons.
So what if someone bullied you or you failed a test or some thing. You can always move on
You might be interested to read about the gut-brain connection...or hear online lectures. Our internal environments have a powerful effect on our moods, behavior, etc. Of course being bullied, etc. are real causes as well.
This is amazing how all of this happens. its mind blowing
very imformative video. looks like a lot of work was put into this video. Thanks again Ted-Ed!
I really liked the video because it is very descriptive and ilustrative.
Love love love it ❤ !! So helpful was reading lippincott and couldn't imagine the concept, thanku for the video it makes the topic so much easier!
I know science hates the word, but damn, this process is mystical.
Wow, our bodies are capable of amazing things. Never take them for granted.
Very lucidly explained ! Thanks
