what are/is epigenetics?
In: 2
Your DNA is like the giant book of procedures to deal with different situations in a natural disaster. If power substations are taken out, you have a plan to get power restored to hospitals first and maybe deliver generators to a central location. If there is massive flooding you might mobilize a bunch of helicopters and boats to rescue people. Etc.
Epigenetics is basically how life deals with different situations while using the same basic blueprint (your genome). You do not use all of the genes your DNA encodes for. Epigenetics will determine which genes are active and how active they are. It’s incredibly complex and can be very subtle. We’ve barely scratched the surface on epigenetics and there’s still a lot we don’t know.
