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-induced transcriptional silencing — (RITS) is a form of RNA interference by which short RNA molecules such as small interfering RNA (siRNA) trigger the downregulation of transcription of a particular gene or genomic region. This is usually accomplished by posttranslational… … Wikipedia
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 silencing — refers to a family of gene silencing effects by which the expression of one or more genes is downregulated or entirely suppressed by the introduction of an antisense RNA molecule. The most common and well studied example is RNA interference, in… … 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 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 — Die Ribonukleinsäure ist eine Nukleinsäure, das heißt eine Kette aus vielen Nukleotiden (ein so genanntes Polynukleotid). Im internationalen und im wissenschaftlichen Sprachgebrauch wird die Ribonukleinsäure mit der englischen Abkürzung RNA… … Deutsch Wikipedia
