has part tRNA 3'-terminal CCA addition https://github.com/geneontology/go-ontology/issues/19854 GO:0001680 biological_process Post-transcriptional addition of the terminal 3' CCA sequence to a tRNA which does not encode this sequence within the primary transcript. CCA addition proceeds by the sequential addition of CTP, CTP, and then ATP to the 3' end of the tRNA, yielding a diphosphate with each nucleotide addition.
