DNA methylation

   Also found in: Wikipedia 0.01 sec.
DNA methylation  (mth-lshn)
The modification of a strand of DNA after it is replicated, in which a methyl (CH3) group is added to any cytosine molecule that stands directly before a guanine molecule in the same chain. Since methylation of cytosines in particular regions of a gene can cause that gene's suppression, DNA methylation is one of the methods used to regulate the expression of genes.
