WebNov 9, 2015 · In plants DNA methylation is found at the symmetric CG or CHG (where H = A, C, or T) sites or at nonsymmetric CHH sites. CG and CHG methylation are maintained at high fidelity following DNA replication due to activity of maintenance methyltransferases such as MET1 or chromomethylase (CMT) 3 ( 3 , 4 ), whereas CHH methylation (mCHH) … WebDNA methylation regulates gene expression by recruiting proteins involved in gene repression or by inhibiting the binding of tra … In the mammalian genome, DNA methylation is an epigenetic mechanism involving the transfer of a methyl group onto the C5 position of the cytosine to form 5-methylcytosine.
