I'm working on a continuous series to explain this relatively new field of genetics. The epigenome is a series of chemical changes affecting the genome without altering the DNA sequence itself. Read more about what epigenetics is...

One form of epigenetic change is DNA methylation. The enzyme DNA methyltransferase is responsible for adding a methyl group to the nucleotide cytosine, one of four in the DNA sequence. Read more about how DNA methylation affects gene expression...
