Answer 1

Epigenetics :- it is the study of changes in gene expression without DNA sequences alteration.

Epigenetics :- It is the study of change in gene expression without change in DNA sequence. It is a natural process. example: - DNA methylation :- means addition of methyl group in DNA to prevent other gene expression
