DNA methylation is a process by which methyl groups are added to DNA. Methylation modifies the function of the DNA, typically acting to suppress gene transcription.NA methylation suppresses the expression of endogenous retroviral genes and other harmful stretches of DNA that have been incorporated into the host genome over time. DNA methylation also forms the basis of chromatin structure, which enables a single cell to grow into multiple organs or perform multiple functions.
DNA methylation occurs where a methyl group is covalently bonded to a cytosine that is immediately followed by a guanine (CpG). The functional result of DNA methylation depends on the location of the methylated CpGs. In many cases it is associated with gene silencing when the CpGs are in the promoter regions. However, methylation can occur within a gene and the observed effect is an increase in transcriptional activity.
