The methylation of histone H3-K27 was proved to be linked to several silencing phenomena including homeotic-gene silencing, X inactivation and genomicimprinting.

Because we have identical DNA in each of our cells, our bodies have mechanisms, such as DNA methylation, to control which genes are expressed in certain cell types-a process called genomicimprinting.
