General Genetics
DNA methylation is a biochemical process involving the addition of a methyl group to the DNA molecule, typically at the cytosine base, which can affect gene expression without altering the underlying DNA sequence. This modification plays a crucial role in regulating various biological processes, including development, genome organization, and inheritance patterns, by influencing how genes are expressed and silenced in different contexts.
