Awaken the Living Awareness Within Glossary
Epigenetics is the study of phenotype changes that do not involve alterations in the DNA sequence. Epigenetics most often denotes changes in a chromosome that affect gene activity and expression. The term also refers to the changes themselves: functionally relevant changes to the genome that do not involve a change in the nucleotide sequence. Examples of mechanisms that produce such changes are DNA methylation and histone modification, each of which alters how genes are expressed without altering the underlying DNA sequence. See also closely related term Human Genome (DNA).
