Epigenetics basically focuses on processes that regulate how and when certain genes are turned on and turned off, while epigenomics focuses on analysis of epigenetic changes across many genes in a cell or entire organism.
Meaning of epigenome
In the complete set of DNA in a cell (genome), all of the modifications that regulate the activity or (expressions) of the genes is known as the epigenome. Because epigenetic changes helps to determine whether genes are turned on or turned off, they influence the production of proteins in cells.
Meaning of epigenetic changes
Epigenetics is defined as the study of how our behaviors and environment can cause changes that affect the way our genes work. Unlike genetic changes, epigenetic changes are reversible in nature and do not change our DNA sequence, but they can change how our body reads a DNA sequence.
