Methylation
Addition of methyl groups. In histo-chemistry methylation is used to esterify carboxyl groups and remove sulfate groups by treating tissue sections with hot methanol in the presence of hydrochloric acid. (From Stedman, 25th ed)
Year introduced: 1968
DNA Methylation
Addition of methyl groups to DNA. DNA methyltransferases (DNA methylases) perform this reaction using S-ADENOSYLMETHIONINE as the methyl group donor.
Year introduced: 1997
RNA Methylation
The addition of a methyl group to one of the NITROGEN atoms on a NUCLEOTIDE base in an RNA molecule.
