WebDNA methylation provides a pivotal layer of epigenetic regulation in eukaryotes that has significant involvement for numerous biological processes in health and disease. The function of methylation of cytosine bases in DNA was originally proposed as a "silencing" epigenetic marker and focused on promoter regions of genes for decades. WebDNA methylation stably alters the expression of genes, and so it occurs as cells divide and differentiate from embryonic stem cells into specific tissues. And so this is essential for normal development, and is associated with other processes, such as genomic imprinting, and x-chromosome inactivation, topics for another discussion. ...
