Root Explanation

Epigenetic → It is formed from "epi-" (meaning upon or above) and "genetic" (from Greek "genesis", meaning origin or birth). The term refers to processes that affect gene activity without altering the DNA sequence itself, essentially acting upon the genetic material.

Memory Tip

Think of 'epi-' meaning 'upon' or 'above' and 'genetic' relating to 'origin' or 'birth' — this helps you remember that epigenetic processes act upon the genes without changing their fundamental structure.
