PiRNAs are small non-coding RNAs that guide the silencing of transposons and other targets in animal gonads. In Drosophila female germline. many piRNA source loci dubbed "piRNA clusters" lack hallmarks of active genes and exploit an alternative path for transcription. which relies on the Rhino-Deadlock-Cutoff (RDC) complex. https://allfixelectricales.shop/product-category/motor-carbon-brushes/
