DNA Methylation

Meaning

DNA Methylation is a fundamental epigenetic mechanism involving the addition of a methyl group to the cytosine base within a DNA sequence, typically at CpG sites. This biochemical process generally functions to repress gene transcription without altering the underlying nucleotide sequence. In the context of hormonal health, it critically influences the expression of hormone receptor genes and metabolic enzymes. Understanding methylation patterns offers insight into long-term physiological programming.
