Small rna sorting: matchmaking for argonautes
WebMicroRNAs represent nonprotein coding small RNA molecules that are very stable to degradation and responsible for gene silencing in most eukaryotic cells. Increased evidence has been accumulating over the years about their potential value as WebMar 1, 2012 · microRNAs (miRNAs), a class of non-coding small RNAs, play important roles in gene regulation and impact a myriad of biological processes and diseases.1Most miRNAs are generated by the canonical biogenesis pathway2(Fig. 1). miRNA genes are transcribed by RNA polymerase II (RNAP II) into primary miRNA transcripts (pri-miRNAs), which are …
