RNA interference — (RNAi) is a mechanism that inhibits gene expression at the stage of translation or by hindering the transcription of specific genes. RNAi targets include RNA from viruses and transposons (significant for some forms of innate immune response), and … Wikipedia
RNA polymerase II — (also called RNAP II and Pol II) is an enzyme found in eukaryotic cells. It catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA. [cite journal | author = Kronberg, R.D. | title = Eukaryotic… … Wikipedia
RNA triphosphatase — is an enzyme used to cleave the γ phosphate out from the 5 end NTP of a newly synthesized mRNA, so that 5 capping can be performed … Wikipedia
RNA — For other uses, see RNA (disambiguation). A hairpin loop from a pre mRNA. Highlighted are the nucleobases (green) and the ribose phosphate backbone (blue). Ribonucleic acid (English pronunciation: /raɪbɵ.njuːˌkleɪ.ɨk ˈæsɪd/), or RNA, is one of… … Wikipedia
RNA world hypothesis — A comparison of RNA (left) with DNA (right), showing the helices and nucleobases each employs. The RNA world hypothesis proposes that life based on ribonucleic acid (RNA) pre dates the current world of life based on deoxyribonucleic acid (DNA),… … Wikipedia
RNA polymerase — RNAP from T. aquaticus pictured during elongation. Portions of the enzyme were made transparent so as to make the path of RNA and DNA more clear. The magnesium ion (yellow) is located at the enzyme active site. RNA polymerase (RNAP or RNApol) is… … Wikipedia
RNA splicing — In molecular biology and genetics, splicing is a modification of an RNA after transcription, in which introns are removed and exons are joined. This is needed for the typical eukaryotic messenger RNA before it can be used to produce a correct… … Wikipedia
RNA splicing — SYN: splicing (2). * * * the removal (splicing out) of introns from a primary transcript and the subsequent joining (splicing together) of exons in the production of a mature RNA molecule … Medical dictionary
Transfer RNA — The interaction of tRNA and mRNA in protein synthesis tRNA Identifiers Symbol tRNA … Wikipedia
Long non-coding RNA — Long noncoding RNAs (long ncRNAs) are generally considered (somewhat arbitrarily) as non protein coding transcripts longer than 200 nucleotides. This limit is due to practical considerations including the separation of RNAs in common experimental … Wikipedia
