WebbIn Minotaur mutant ovaries, the interactions between Zucchini and piRNA precursors are greatly diminished. Since loss of either gene leads to the accumulation of piRNA primary transcripts, we concluded that Minotaur might be required for either the recruitment of piRNA precursors to Zucchini and/or the endonuclease activity of Zucchini in vivo to … Webb27 jan. 2024 · piRNAs have the following six characteristics: 1) piRNAs are approximately 26–31 nucleotides in length, whereas microRNAs and siRNAs have lengths of 21–23 nucleotides. piRNAs are independent of the Dicer enzyme and are produced by a single-stranded precursor ( Weng et al., 2024 ).
