WebDNA methylation is an epigenetic mechanism that occurs by the addition of a methyl (CH 3) group to DNA, thereby often modifying the function of the genes and affecting gene expression. The most widely characterized DNA methylation process is the covalent addition of the methyl group at the 5-carbon of the cytosine ring resulting in 5 ... Web5-Methylcytosine (5mC) is an enzymatically produced modified cytosine base that has been known to exist in mammalian DNA for about 70 years. These decades of research have provided important clues as to its presumed functional role but there is no complete understanding yet.
