title: The postnatal methylation of transfer ribonucleic acid in brain. Evidence for the methylation of precursor transfer ribonucleic acid.
abstract: Incubation of 3-day-old rat brain with L-[methyl-3H]methionine resulted in the rapid labeling of low-molecular-weight cytoplasmic RNA. Electrophoresis in 15% polyacrylamide gels provided evidence for the methylation of precursor tRNA molecules, and high-performance liquid chromatography demonstrated N2-methylguanine to be the predominant methylated base formed during the first 2 min of labelling.
