DNA Methylation Influence

Meaning

DNA Methylation Influence refers to the profound impact that the addition of a methyl group to the cytosine base of DNA has on gene expression and cellular function without altering the underlying genetic sequence. This epigenetic modification acts as a crucial molecular switch, effectively turning genes ‘on’ or ‘off’ in response to environmental, lifestyle, and hormonal signals. The pattern of methylation is dynamic and highly responsive, serving as a primary mechanism linking external factors to the cell’s genetic programming and playing a key role in the aging process.
