This is because the epigenetic modifications act like switches, turning on the gene that is most needed in a particular cell at a particular time, so helping to control gene acti ...

DNA methylation
... The molecular basis of epigenetics is complex. It involves modifications of the activation of certain genes, but not the basic structure of DNA. Additionally, the chromatin proteins associated with DNA may be activated or silenced. This accounts for why the differentiated cells in a multi-cellular ...
