Molecular Biology Dna Methylation
Molecular biology DNA methylation is a process in which certain molecules chemically modify a gene by attaching a small molecule known as a methyl group. This process causes changes in gene expression, which means that the gene can be turned on and off like a switch. DNA methylation is essential for normal cellular development and plays a role in many processes such as cancer, aging, and the regulation of gene expression. It is also used to study epigenetic inheritance, which is the transmission of traits that are not passed on genetically. Molecular biology DNA methylation has enormous implications for medical research, diagnostics, and drug development.
