Epigenetics refers to covalent modification of DNA, protein, or RNA, resulting in changes to the function and/or regulation of these molecules, without altering their primary sequences. Epigenetics has helped the field of genetics it allows scientist to alter the way genes are read and to tell if the gene is active or inactive. Epigenetics can be used for many great causes, such as preventing leukemia or stop aging in adults. The preventing of leukemia is done by the the scientist finding the gene that eliminates tumors and then making it become an active gene, thus eliminating the leukemia. The stopping of aging in adults is very similar to the way leukemia is cured but instead of activating a gene, a gene is switched off. Using epigenetics
