Biogenesis of pirna
WebJan 27, 2024 · In piRNA biogenesis, piRNA clusters are located in transposon elements. Thus, piRNAs are thought to be involved in transposon silencing through epigenetic mechanisms ( DiGiacomo et al., 2013 ). Transposable elements shift and replicate by inserting themselves into the genome ( Tóth et al., 2016 ).
