How mRNA helped save lives: DNA Transcription: Crash Course Biology #34

You’ve probably heard of mRNA, thanks to the COVID-19 vaccine. But what is mRNA exactly? In this episode of Crash Course Biology, we learn about the role of messenger RNA in living things and how it decodes our DNA instruction manual through transcription.

Messenger RNA 1:21
Transcription 3:48
Processing & Splicing 5:05
The Central Dogma 7:00
Alternative Splicing 8:39

It’s amazing to me that biologists have learned how DNA/RNA works well enough that we can now splice genes and manufacture mRNA fragments so we can treat a number of diseases and disorders this way.

Yay! As a bioinformatician working with a lot ofnRNA data I can send this video to my students.

The molecular machines that operate away in our cells are so fascinating.

Dr Sammy continues to be amazing - that "devour a good book" line had such excellent delivery it had me laughing for minutes!

Oh I can't wait to read these comments 😂😂😂

Loving this series, really informative, fun and engaging and that's coming from someone who has always struggled to really engage with cellular biology in particular. Also I love the host choice, Dr Sammy is great!

[gregmiller]

i was totally unaware of how the covid flu shot worked...now i might get one because i haven't yet due to allergic reaction to the shingles for the education ! :)

[adamphilip]

Really good coverage of the covid vaccine for this context!

[pinktights]

Thank you for the free education. I payed a small fortune at the University.❤❤❤😂😂

[turtler]

i'm too early for the translation video when my test is in a few days :( unfortunate but this video was still helpful :)

[starc.]

fantastic video can you follow it up with more?

[jawaharkonathala]

Can you please give examples which help students from other countries also to understand? Like I didn't understand the platypus playground.

[beo_freo]

Unrelated question, but are those jellyfish in the background real? :c

[Nick-zpwk]

So uhhh, why did Hank stop hosting again? 🌝

It is important to add any risks involved in such a crash course; IMHO it is irresponsible not to. Please research off-target effects. Any potential risks involved should also be mentioned so that we can be informed. Or maybe there are no risks? But that is unlikely and certainly long term unknown. Thank You!!

As king David under inspiration said we are wonderfully made.. praise God Almighty

This and HurkaDurrGesagt are transparently prop-up-ganduhrr at this point.
