Allele-particular DNA methylation a widespread phenomenon.
This contradicts earlier assumptions that epigenetic indicators are generally equal across both copies of a given area of the genome, except at a small amount of known imprinted genes. Sequencing the genome was only the first step in our quest to understand how genes are expressed and regulated. Epigenetics may be the scholarly research of alterations to gene function, believed to happen independently of the DNA sequence traditionally. (more…)
