This is accomplished through … 1 These include DNA methylation, histone density and posttranslational modifications, and RNA-based mechanisms. This type of gene regulation is called epigenetic regulation. It begins with a short introduction of the basic players that take part in epigenetic control (DNA, histones and the histone modification code), and then moves on to describe the connection of epigenetic mechanisms with another fundamental cell process, transcription. Distinct epigenetic modifications show specific correlations with transcription. Instead, these changes are temporary (although they often persist through multiple rounds of cell division) and alter the chromosomal structure (open or closed) as needed. 1.
