Epigenomics refers to the study of epigenetics modification at the genomic level. It studies the modification of non-DNA sequence changes in the context of "omics," which has led to an increase in genomic research and a new point of view: For the genome, not only the DNA sequence contains genetic information, but its modification can also record genetic information.
