    6400   TRNA Modification  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. 
    8033   TRNA Processing  The Process in Which a Pre TRNA Molecule Is Converted to a Mature TRNA Ready For Addition of an Aminoacyl Group. 
    8616   Queuosine Biosynthetic Process  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.
