methylation - (pronounced) (MEH-thuh-LAY-avoid) chemical reaction in the body that attaches a small molecule called a methyl group to DNA, proteins, or other molecules. The addition of methyl groups can affect how some molecules work in the body. For example, methylating the DNA sequence of a gene can turn off the gene so it doesn't make a protein. Changes in the methylation patterns of genes or proteins can affect a person's risk of developing a disease such as cancer
