DNA methylation is a process that plays a crucial role in regulating gene expression and maintaining genomic stability. However, there are several other terms that can be used interchangeably with DNA methylation. Some synonyms for DNA methylation include DNA demethylation, epigenetic modification, and DNA methyltransferase activity. DNA demethylation is the process of removing methyl groups from DNA, which can also alter gene expression. Epigenetic modification refers to any heritable changes in gene expression that are not related to changes in the DNA sequence itself, including methylation. Lastly, DNA methyltransferase activity refers to the enzymes responsible for adding methyl groups to DNA.
