Web30 nov. 2024 · DNA methylation is one of the earliest epigenetic modifications to be discovered in human beings. It involves the transfer of methyl (CH3) groups to the C5 position of cytosine bases that comprise deoxyribonucleic acid (DNA) to produce 5-methylcytosine (5mC) – the reaction is catalyzed by a family of enzymes called DNA … WebDNA methylation represents the best characterized form of epigenetic modification. DNA methylation is written onto the genome by two methyltransferases, known as Dnmt3a and Dnmt3b. These enzymes catalyze the addition of a methyl group to the fifth carbon of the cytosine DNA base.
