Introduction to Epigenetics/Epigenomics
... • Epigenetics refers to the study of changes in the regulation of gene activity and expression that are not dependent on gene DNA sequence. • While epigenetics often refers to the study of single genes or sets of genes, epigenomics refers to more global analyses of epigenetic changes across the enti ...
