WebAug 15, 2024 · Types of epigenetic changes include: DNA Methylation DNA methylation works by adding a chemical group to DNA. Typically, this group is added to specific places on the DNA, where it blocks the proteins that attach to DNA to “read” the gene. This chemical group can be removed through a process called demethylation.
