What is DNA Methylation?
DNA methylation is an important change in the genome that controls gene activity without changing the DNA sequence. This change involves adding a methyl group (CH₃) to the DNA, usually at certain points in the DNA sequence. DNA methyltransferases (DNMTs) catalyze this addition by transferring a methyl group from S-adenosylmethionine (SAM) to cytosine. As a fundamental...
