WebAug 5, 2003 · Abstract. MicroRNAs (miRNAs) are endogenously encoded small noncoding RNAs, derived by processing of short RNA hairpins, that can inhibit the translation of mRNAs bearing partially complementary target sequences. In contrast, small interfering RNAs (siRNAs), which are derived by processing of long double-stranded RNAs and are often of … WebControl of gene expression by these small, noncoding RNA molecules was first observed in 1993, when a team of scientists discovered a small, double-stranded RNA (dsRNA) in nematode (...
