Small rna function

Small nuclear RNA (snRNA) is a class of small RNA molecules that are found within the splicing speckles and Cajal bodies of the cell nucleus in eukaryotic cells. The length of an average snRNA is approximately 150 nucleotides. They are transcribed by either RNA polymerase II or RNA polymerase III. Their primary function is in the processing of pre-messenger RNA (hnRNA) in the nucleus. They have also been shown to aid in the regulation of transcription factors (7SK RNA) o… WebIts job is to match an mRNA codon with the amino acid it codes for. You can think of it as a kind of molecular "bridge" between the two. Each tRNA contains a set of three nucleotides called an anticodon. The anticodon of …

Non-coding RNA - Wikipedia

Small RNA (sRNA) are polymeric RNA molecules that are less than 200 nucleotides in length, and are usually non-coding. RNA silencing is often a function of these molecules, with the most common and well-studied example being RNA interference (RNAi), in which endogenously expressed microRNA (miRNA) or exogenously derived small interfering RNA (siRNA) induces the degradation of complementary messenger RNA. Other classes of small RNA have been identified… WebOur exploration of the physiological functions of probiotic bacteria hopes to elucidate the role of small regulatory RNAs or non-coding RNAs in regulating gene expression within the human body.
