MicroRNAs (miRNAs) are 21- to 24-nucleotide (nt) RNAs that are the final products of nonprotein-coding genes. miRNAs are processed from single-stranded precursors that form hairpin structures, with the miRNAs residing in one arm of the stems. miRNAs were first isolated and recognized as regulators of protein-coding genes through forward genetic screens in Caenorhabditis elegans, but were not recognized as universal regulators of gene expression in animals until three landmark studies in year… CONTINUE READING
