A microRNA (abbreviated miRNA) is a small single-stranded non-coding RNA molecule (containing about 22 nucleotides) found in plants, animals and some viruses, that functions in RNA silencing and post-transcriptional regulation of gene expression. miRNAs function via base-pairing with complementary sequences within mRNA molecules. microRNAs (miRNAs) represent a novel class of genome-encoded eukaryotic regulatory RNAs that silence gene expression posttranscriptionally. Although the proteins mediating miRNA biogenesis and function have been identified, the precise mechanism by which miRNAs regulate the expression of target mRNA ….

c) MicroRNAs regulate target genes by binding to complementary sequences on one DNA strand of the target gene. d) MicroRNAs normally regulate the expression of just a single target gene. Explanation 6.2 All are false. There are other types of tiny RNA, including piRNAs and endogenous siRNAs.
