DNA methylation

A) is a form of transcriptional regulation of gene expression.
B) is a form of post-translational regulation of gene expression.
C) is a form of post-transcriptional regulation of gene expression.
D) none of the above

DNA Methylation

A biochemical process where a methyl group is added to the DNA molecule, often affecting gene expression without altering the sequence.

Transcriptional Regulation

The mechanisms and controls that govern the conversion of DNA to RNA, influencing gene expression levels.
