DNA and RNA epigenetics, once thought to be separate, have now been found to work together to fine-tune gene expression.

Like Chipper long suspected -- the two are inseparable, as I've always maintained !

Scientists have uncovered a new way that cells control their genes — and it may rewrite our understanding of "epigenetics."

Epigenetics is a form of DNA modification that doesn't affect the DNA sequence itself. Instead, it describes when chemical groups attach to specific genes, thus switching those genes on or off, or else changing the 3D shape of chromosomes.

Now, in a study published Jan. 17 in the journal Cell, scientists have uncovered a whole new method of gene regulation that involves epigenetic tweaks made to both DNA and its molecular cousin RNA, at the same time.
