WebJan 29, 2014 · In normal development, all cells turn off genes they don't need, often by attaching a chemical methyl group to the DNA, a process called methylation. Historically, scientists believed methyl groups could only stick to a particular DNA sequence: a cytosine followed by a guanine, called CpG. But in recent years, they have been found on WebMar 23, 2024 · Typically, DNA methylation turns genes off, while demethylation turns genes on.
