WebJun 24, 2024 · 6. Gene Expression. DNA methylation, a specific subset of methylation in which methyl groups are attached to certain segments of DNA, tells the body what genes should be turned on and off. Essentially, it can help turn off bad genes that might otherwise lead to suboptimal cellular function or certain diseases, explains Dr. Rawls. WebNov 9, 2024 · One of the ways by which a cell turns off specific genes is by the reversible addition to the DNA of a minuscule chemical called a methyl group at the precise location of that specific gene.
