RNA polymerase — A polymerase is an enzyme that catalyzes the joining of many smaller molecules (called monomers) to form a big molecule (a macromolecule). RNA polymerase is a unique enzyme that makes (synthesizes) the macromolecule RNA using DNA as the template … Medical dictionary
RNA-dependent RNA polymerase — (RDRP), or RNA replicase, is an enzyme that catalyzes the replication of RNA from an RNA template. This is in contrast to a typical RNA polymerase, which catalyzes the transcription of RNA from a DNA template.Viral RDRPs were discovered in the… … Wikipedia
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-directed RNA polymerase — RNA di·rect·ed RNA po·lym·er·ase (dĭ rekґtəd pə limґər ās) [EC 2.7.7.48] an enzyme of the transferase class that catalyzes the template directed step by step addition of ribonucleotides to the 3′ end of a growing… … Medical dictionary
RNA-directed DNA polymerase — RNA di·rect·ed DNA po·lym·er·ase (dĭ rekґtəd pə limґər ās) [EC 2.7.7.49] an enzyme of the transferase class that catalyzes the template directed, step by step addition of deoxyribonucleotides to the 3′ end of a DNA… … Medical dictionary
Template — may mean:*a stencil, pattern or overlay used in graphic arts (drawing, painting, etc) and sewing to replicate letters, shapes or designs *a pre developed page layout in electronic or paper media used to create new pages from the same design,… … 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 — 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
