Transcription and mRNA processing | Biomolecules | MCAT | Khan Academy

Introduction to transcription including the role of RNA polymerase, promoters, terminators, introns and exons.

MCAT on Khan Academy: Go ahead and practice some passage-based questions!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

This video is supposed to be for high school students and I'm a med student learning the exact same material 😂

[numannedimayvaz]

this dude is so damn amazing.
His courses are free PLUS he hasn't any ads in his videos. Much Respect for this guy!

[sleepyduck]

the fact that you can digest all categories of subjects and then teach is mind boggling!

[Devilsfannumber]

if anyone wanted to know:
spliceosomes​ are what cut out sections from the RNA strand to remove the introns and leave the exons

I have no idea how you taught me something I've been studying for two weeks in 10 minutes and I understood perfectly. I wish you were my professor! Keep it up for the pre-med students please!!!

[kyloxd]

Anyone else feel the passion in his voice when he talks about these said topics?

[janetchiang]

it's so weird how you always upload topics about exactly what i'm learning in class!

[rubyyxlc]

I wish I would have found this while I was in microbiology, You explained in ten minutes what I couldn't even get from tutoring.

[smol_chilli_pepper]

I never imagined that one day Khan Academy videos would become so nostalgic to me

[toddsecor]

This person has helped me better understand chemistry, trigonometry, calculus, and now biology. He is truly amazing. He should be the dean of MIT.

[Testimonyofabutterfly]

this was super helpful for learning this process! I am in awe of the creator God and his ability to make such a complex and beautiful process within such a small structure!!! Praise Jesus

[shinysunglasses]

This is amazing! I found it hard to understand in class because of how shallow it was, but with more details it makes perfect sense! Thanks a lot.

[anuradhawijethunga]

This was really helpful for my last minute exam preparations ❤️❤️❤️ If it wasn't for youtube, I would've failed my uni exams.

[sarahfalcone]

This helped me a lot to understand the processes in the different cells. Thank you a lot!

Great video - thank you. I liked the very clear explanation of Ribosomal RNA (that it doesn't need anything else to code, compared to the DNA where it needs Helicase, RNA Primers, Ligase, etc.) I also really enjoyed learning about the difference between the mRNA in prokaryotes vs. Eukaryotes. It's interesing that the Introns do not have a specific purpose, so the mRNA, is made up of what's left over after the splicing takes place (exons) of that "pre- mRNA".

Again - I greatly enjoyed this video, thank you!

[JorgeRamos-xwdy]

Wonderful! I'm getting my YouTube degree. I navigate from MIT to Harvard to UC Berkeley etc...all for free lol.
I wish this were around when I went to school. Thank you for the wonderful videos.

Gene editing eugenics, using aborted baby cells and tissues also, GMO nanotech particles

[astrovation]

I like how you don't just pass on the material but also pass on the passion

[cristianalima]

I wish everything good for you, you just saved my exam! Thank you!

[spxtfxre]

Mr. Khan, you seem like an awesome human being to me. I really wish you could coach me in person. I got only 16 days left before my 12th grade final examinations start. Thanks a lot for doing what you're doing. That's really great work. Keep it up. I will donate when I am able to. ❤❤
