"DNA mythelation"


....OK, I give up. What is this?

[muawiyah]

It's an epigenetic process. In some instances methyls get into cell nucleus and manage to work their way down a strand of DNA "blocking" expression of genes further down the line.

There's another process where something gets "de-methylated" and genes thought to be dormant get expressed.

The genes don't change at all.
