DNA methylation
... (1) CpG islands are unmethylatable by the existing de novo methytransferases. However, this is unlikely because they become densely methylated on the inactive X chromosome and in cancer cells. (2) CpG islands are protected from methylation by the binding of factors which exclude Dnmts. (3) CpG islan ...
