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.

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

[@pandaninja001]

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

[@osanneart9318]

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

[@JWhitePWC]

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...

[@digdugdoggy]

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

[@sbfoster]

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

[@Didomate]

I did not expect them to upload on a Thursday

[@Meowzine]

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

[@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

[@Davlavi]

Another great video.

[@vintagewitching]

You are amazing 🙌

this is my coconut crab carl and I feed him pilots

[@joshcoyle6223]

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

[@liaplays4943]

Homeostasis pleaseeeee😭😭😭

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