MicroRNAs (miRNAs) are endogenously expressed single-stranded ~21M-bM-^@M-^S23 nucleotide RNAs that inhibit gene expression post-transcriptionally by binding imperfectly to elements usually within the 3M-bM-^@M-2untranslated region (3M-bM-^@M-2UTR) of mRNAs. Small interfering RNAs (siRNAs) mediate s...
