The covalent alteration of one or more nucleotides within an RNA molecule to produce an RNA molecule with a sequence that differs from that coded genetically. The chemical reactions and pathways resulting in the formation of 7-methylguanosine, a modified nucleoside that forms a cap at the 5'-terminus of eukaryotic mRNA. The chemical reactions and pathways involving queuosines, any of a series of nucleosides found in tRNA and having an additional pentenyl ring added via an NH group to the methyl group of 7-methylguanosine. The pentenyl ring may carry other substituents. The chemical reactions and pathways involving 7-methylguanosine, a modified nucleoside that forms a cap at the 5'-terminus of eukaryotic mRNA. The process by which a pre-tRNA molecule is converted to a mature tRNA, ready for addition of an aminoacyl group. The covalent alteration of one or more nucleotides within a tRNA molecule to produce a tRNA molecule with a sequence that differs from that coded genetically. The chemical reactions and pathways resulting in the formation of guanine, guanine riboside, a nucleoside with a wide species distribution. The chemical reactions and pathways resulting in the formation of queuosines, any of a series of nucleosides found in tRNA and having an additional pentenyl ring added via an NH group to the methyl group of 7-methylguanosine. The pentenyl ring may carry other substituents.
