Cytosine nucleotides having methyl groups
WebJul 11, 2012 · A family of DNA methyltransferases (Dnmts) catalyzes the transfer of a methyl group from S-adenyl methionine (SAM) to the fifth carbon of cytosine residue to … WebDNA methylation is the process through which a methyl group is added to DNA nucleotides. The most common form of this occurs at the 5-carbon position of cytosine (5 methylcytosine or 5mC). DNA methylation can stably alter the gene expression of a cell, which may direct processes like stem cell differentiation and genomic imprinting.
