Epigenetics: A Primer in Sketches [Link]
Epigenetics. So hot right now.
I study epigenetics in my lab. (That’s right, I’m hot.) When someone asks me what that means, I give the brief definition: “It’s the study of changes in gene expression without a change in the actual DNA sequence.” “Like, molecules or proteins can bind to the physical DNA and affect whether the DNA is transcribed.” “Y’know?”
If you’re looking for a more technical, yet understandable, explanation, head over to the Sketch Overview of Epigenetics at Genes to Brains to Mind to Me. The author is a great artist, as you can see above, and the primer gives a good overview of epigenetics basics to keep you hip to the scene.
