What i love about this channel is the range of topics you cover. Maths, biology, biochemistry, chemistry even personal finances. How can you be so smart man
i’m saying dude is a total saint for putting this out for free. Still a year after your comment it’s saving me
man, I love you. you basically saved my career and I have learned more in 20 minutes than 10 weeks.
Been there!
Love TH-cam
😭😭😭😭
This guy deserves all my money that's going for my stupid professors
You said it like the backbencher guy, very ruddde
Which one is the sense and anti-sense strand
@@uthmanrashad775 anti-sense and strand is in relation to transcription, the anti-sense strand is the template that is the strand used to synthesize the rna and the sense strand is the non template. I don't know if this makes sense but yh
@@_sakura.. yh thx. I was thinking about semi-conservative replication and whether DNA polymerase moves from the 5’ to 3’ end (sense strand). I just got a bit confused
@@uthmanrashad775 oh ok, so you're good now?
Me: Too bad The Organic Chemistry Tutor doesn't cover biology.
The Organic Chemistry Tutor:
Right. This is saving my ass
The goat 😂😂😭😭
The Organic Chemistry Tutor: hold my Camtasia Studio
you all prolly dont care but does anyone know of a tool to log back into an instagram account??
I somehow forgot my login password. I would appreciate any tips you can offer me

literally the GOAT of STEM
SKINNNNNY LEGEND DOING CHEMISTRY, CALC, AND BIO QUEEN
Do not forget his physics videos that save me. He is OG
Yasssss
And PHYSICS
and vector calculus too this man is a legend
what would it take for you to do a face reveal??
Why lmao
Lol
we are big fans
right?
To honest ooo, I have been leaning on this plat form for years but I never see this guys
Wooooh the best chemistry teacher I have ever seen, I got 95 after watching his quantum theory now teaching biology too great
You’re every student’s asset, thank you! Your simplification and explanations are beyond comprehension.
I can't even express with words how thankful I am because of your videos. I have been struggling with genetics since the beginning of this semester and you literally explain everything so smoothly and well!!! I understood everything in 20 min. I usually go to class and I get desperate because I don't get what the teacher is saying in her lectures. Thank you so much for all this videos !!!!!!!!!!!!!!!!!!!!
Daniel Heath?!
Perfect timing. Bio test tomorrow XD
Nicholas Pianosi same
Bio SAT, gotta cram everything in now
Me rn 😩
There is nothing that this man cannot teach....One must not need to know everything to tach other, one only needs the ability to make others understand what you know in the easiest way...this man does it all
I just want to say that you have been of great help and that you don't get the recognition you deserve.
I have watched many different videos but nothing compares to this. May God bless you and give you more wisdom. Thanks
This guy is too good, like I had to purse the video to compliment you first.
I've been struggling with this particular topic but you broke everything down to the simplest form for me, I love your teaching. God bless you abundantly for me.
Thank you so much, for this video , I sat in class for 2hrs and didn't understand anything about DNA Replication.... I listened to this video for 10 mins , I now got the concept
Preparing for a test today and I've being finding so difficult to accumulate all the activities going on in the replication properly and less confusing, and you just made that very possible.
Thank you, I'm very grateful ♥️
I've had to have watched my professor's videos at least 5 times and it still flew over my head- one watch with this video and it's crystal clear. Thanks.
i literally love your teaching style so much. You helped me with algebra and calc and chem and now bio. Your videos are always exactly what I need
I really can not express how grateful i am for your lessons🥺whenever there's something i don't understand i know that i got you!! Thank you so much sir, you really are a blessing in our lives
I was confused about all these stuff, the complex terminology was killing me until I find your video. You are a godsent. Thanks for making such brilliant videos! By far, the best in business.
you have so much value to so many people. you are making your mark on the world by making education possible for so many of us. These videos are a treasure and you are an icon in education. Thank you, really.
as a bio chem major who's minoring in math, I owe you my entire career. You explain everything so well! learning a lot from your videos :)
I love u so much sir & I say that from the bottom of my heart. U have really helped me academically in so many ways & I so much thank u for the effort u put in explaining these concepts. A lot of these university lecturers don’t teach as good as you sir. Much love from Nigeria ❤
gonna make 20 accounts on youtube so that I can like your video 21 times
Single handedly pulling me through my first year bio course.
Thank you 🙏🏾
Le zambie
your videos have gotten me a 4.0 in high school and still using right now in my second year of college. i wish i could tell you how many late nights that these videos have shortened for me... thank you so much
You are one of the best teacher. I had doubt about how okazaki fragments are created. Now it's clear. ❤
Same lol
Once again I'm here praising your work for saving.. literally always savings my grade❤️🥺
God bless you man
As a computer scientist and learning bioinformatics this was very helpful, thank you!
I am crying, thank you. Taking A+P right now and I can't do it, but your videos make me feel like I got this...
This video has taught me what I didn’t understand for weeks and tomorrow is my genetics exam thank you
So far you are the only person I understand who explains this. Thank you so much!!
Damn, this was so well explained, my professor would never put this much effort in her teaching.
You do a really amazing job of introducing the information in a manner that is easily comprehensible. Taking a semi-difficult topic such as DNA replication and making it seem simple is a very underrated skill and you perform it magnificently. Thanks for the video, it was extremely helpful!
My dude I love you... I finished this in first semester but I still love you for uploading this
this man is so cute bro like damn i dont even mind when u stutter that is big cute
oh god.
bruh?
Get in line sweetie 😩
um ok lol
A word of Thanks to this intelligent Young Man!!!
you just an amazing tutor man. you really have the ability to make things look so simple. Thumbs up man
Bro this is soooooo crazy, this guy uploaded this 8hrs ago, I only just did this in class yesterday, and while I was just strolling on TH-cam I randomly found this video
I am so thrilled to see you doing biology sessions!
😅 you're really becoming a tiktok edit. I'm obsessed, you've helped me with two years of school work. Please make more videos relating to biochemistry 😊❤
Thank you so much. I just learned this in class before spring break, we went over it all so fast I got confused, plus all the time from spring break left me with some unknown info. This helped a lot
I love it so much, and I love that you’re being so natural! Thanks 🙏🏽
Great video, I love your voice, it´s so easy to understand and follow (i´m not primarly english speaker) . And the list you showed in the upper right side it´s just the abstract I need to write down like a flash card. Thank you so much, I really appreciate it!
This guy is the mastermind of all the subjects 🔥💕he can clearly explain almost everything 🙌keep growing n building SA's future
I praise your hard work Sir..do you I was stuck in one topic of DNA replication which is of lagging strand. I tried to get online answers but I couldn't find any satisfactory answer but now your video has provided me the solution ....I must say your video is very helpful for me..thank you soooo much 🙏🏼 A Huge Respect From An Indian Student..🇮🇳
God bless your knowledge sir. The one tutor who talk sense
Amazing video brother!!! You spoke in plain english and took your time explaining things.
the best DNA replication video ever. congrats and thank you! GOD bless you 🙏🏻🙏🏻🙏🏻
Easy to follow and understand.
