Occurrence of 7-methylguanine in nucleic acids of rat liver.

V M Craddock, S Villa-Trevino, P N Magee.

Abstract

1. Microsomal and soluble RNA of rat liver have been studied by column and paper chromatography after administration of [Me-(14)C]methionine; evidence was obtained for the occurrence of 7-methylguanine, the methyl group being derived from methionine. 2. No evidence was obtained for the occurrence of 7-methylguanine in DNA.
