WebbSo, each of these different histone tail modifications are associated with a different function. We won't go through all of these, but methylation, which can occur as a single, which we tend to abbreviate as Me, can occur as a monomethylation, dimethylation, so two methyl groups, or trimethylation, three methyl groups.
