How Genes Express Themselves: Crash Course Biology #36

If nearly all your cells have the same DNA, why are muscle cells so different from skin cells? In this episode, we’ll learn how gene expression is regulated in eukaryotes, and how methylating DNA, modifying histones, and messing with translation not only leads to different types of cells, but allows cells to adapt to the world around them.

"The joke ribosomes in my brain must be hitting a stop codon" is a joke that would only ever land here on this channel.

man, genes know how to express themselves a lot better than i do. maybe i can learn more about myself from biology than i once thought...

[pandaninja]

These videos bring me so much joy. I am no longer in school but i really love learning about biology ☺️

Dr Sammy continues to be the best non-Green host of Crash Course since Dr Phil Plait imo

[digdugdoggy]

YES! I LOVE CONSUMING INFORMATION IN EASILY ACCESSIBLE FORMATS! WIN!!!!

[paganizonda]

Sooo good animations, really educated people presenting stuff, i love this channel and its content

Thank you for merging sociology and biology to produce a beautiful takeaway from this lesson. Now that's how you use a platform!

[sbfoster]

I love that these videos are matching up with what we're learning in my genetics class ❤

[Meowzine]

This was great! Your personality really shines and gives the information life. 🧬😄

[Didomate]

I did not expect them to upload on a Thursday

African American proverb😭😭😭😭😭😭lmfao ain’t nobody got time took me off guard

[cheerioscanaries]

Highly enjoyed listening to the epigenetic mechanisms and this video as a whole 😊

[kecilkecilpedas]

I thought Biology was simpler to understand, until I actually watch a Ph.D. tell me something about it, causes my mind to dizzle for a while

[akshatgangwar]

The video is great for learning, especially because your great personality doctor!! You are amazing!!

Anyone know what this methylation associated with opioids I keep hearing about?

If I were a cell, I would be really hesitant to chop and change my mRNA. Luckily, I’m not a cell…
