Did you know?
WebThe most extensively studied kind of epigenetics is DNA methylation, which may affect the activity of a promoter. In areas of a DNA rich in CG repeats (i.e. CpG islands), cytosines may be methylated or an addition of a methyl group, allowing proteins involved in gene repression to recognize it. WebThe exact mechanisms for demethylation are not entirely understood; however, it appears that this process may be mediated by the removal of amino groups by DNA deaminases ( Morgan et al.,...

WebAug 16, 2024 · The methyl groups turn genes on or off by affecting interactions between the DNA and other proteins. In this way, cells can remember which genes are on or off.The second kind of mark, called … WebThe predominant mechanism involves the methylation of DNA and the subsequent recruitment of binding proteins that preferentially recognize methylated DNA. In turn, these proteins associate with histone deacetylase and chromatin remodelling complexes to cause the stabilization of condensed chromatin.
