General Information
Term piRNA processing ID (Ontology) GO:0034587 (Gene Ontology)
Definition A process leading to the generation of a functional piRNA. piRNAs (Piwi-associated RNAs) are a class of 24- to 30-nucleotide RNAs derived from repeat or complex DNA sequence elements and processed by a Dicer-independent mechanism.[ PubMed:23329111 PubMed:24696457 PubMed:34724117 ]
Also Known As "piRNA biogenesis" ; "PIWI-associated RNA biogenesis" ; "PIWI-associated RNA processing"
