/ˌep.ɪ.dʒəˈnet.ɪks/
IELTSAcademic
noun

The study of changes in how genes work without changing the DNA sequence itself. These changes can affect how cells act and can sometimes be passed on.

  • Epigenetics helps explain why twins can become different over time.
  • Scientists are studying epigenetics in cancer research.
  • Diet and stress may affect epigenetics.

Adinary Nuance

Epigenetics is not the same as genetics. Genetics is about the DNA sequence you inherit, while epigenetics is about how that DNA is turned on or off. In simple terms, genetics is the code; epigenetics is part of the control system. Researchers often use epigenetics when they want to talk about gene activity, not gene structure.
