What is DNA Methylation? - News-Medical.net

WebThe most extensively studied kind of epigenetics is DNA methylation, which may affect the activity of a promoter. In areas of a DNA rich in CG repeats (i.e. CpG islands), cytosines may be methylated or an addition of a methyl group, allowing proteins involved in gene repression to recognize it. WebDNA methylation is a biological process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence.
