The posttranscriptional addition of methyl groups to specific residues in a mitochondrial tRNA molecule. The process whereby the base of cytosine at position 34 in the anticodon of a tRNA is post-transcriptionally methylated at the C5 position. Posttranscriptional addition of a methyl group to either a nucleotide or 2'-O ribose in a polyribonucleotide. Usually uses S-adenosylmethionine as a cofactor. The process by which the sugar of a nucleoside in tRNA is modified at the 2'O position. 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 covalent attachment of a methyl residue to one or more monomeric units in a polypeptide, polynucleotide, polysaccharide, or other biological macromolecule. The posttranscriptional addition of methyl groups to specific residues in a tRNA molecule. 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.
