Methylation

In the chemical sciences, methylation denotes the addition of a methyl group on a substrate, or the substitution of an atom (or group) by a methyl group. DNA methylation is a process by which methyl groups are added to the DNA molecule. The topic of methylation is getting its fair share of attention lately, and rightly so. Not all genes are active at all times. In chemistry, the addition of a methyl group to a molecule.
