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.
There are many ways that gene expression is controlled in eukaryotes, but methylation of DNA (not to be confused with histone methylation) is a common epigenetic signaling tool that cells use to lock genes in the off position.lantae are the most highly methylated eukaryotes, with up to 50% of their cytosine residues exhibiting methylation. Interestingly, in Fungi, only repetitive DNA sequences are methylated, and in some species, methylation is absent altogether, or it occurs on the DNA of transposable elements in the genome.
