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-Editing — (deutsch: RNA Editierung) ist ein biochemischer Vorgang innerhalb bestimmter Zellen oder Zellorganellen, der im Verlauf der Genexpression nach der Transkription und vor der Translation stattfinden kann. Der Begriff beschreibt die Modifizierung… … Deutsch Wikipedia
RNA-Edition — RNA Editing (deutsch: RNA Edition) ist ein biochemischer Vorgang innerhalb bestimmter Zellen oder Zellorganellen, der im Verlauf der Genexpression nach der Transkription und vor der Translation stattfinden kann. Der Begriff beschreibt die… … Deutsch 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-Polymerase — Enzymklassifikationen EC, Kategorie … Deutsch Wikipedia
RNA-induced silencing complex — RNA induced silencing complex, or RISC, is a multi protein siRNA complex which cleaves (incoming viral) dsRNA and binds short antisense RNA strands which are then able to bind complementary strands. When it finds the complementary strand, it… … 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 extraction — is the purification of RNA from biological samples. This procedure is complicated by the ubiquitous presence of ribonuclease enzymes in cells and tissues, which can rapidly degrade RNA. [cite journal |author=Peirson SN, Butler JN |title=RNA… … Wikipedia
RNA-OUT — is a non coding RNA that is antisense to the RNA IN non coding RNA. Transposition of insertion sequence IS10 is regulated by an anti sense RNA which inhibits transposase expression when IS10 is present in multiple copies per cell. RNA OUT… … Wikipedia
RNA polymerase III — (also called Pol III) transcribes DNA to synthesize ribosomal 5S rRNA, tRNA and other small RNAs. The genes transcribed by RNA Pol III fall in the category of housekeeping genes whose expression is required in all cell types and most… … Wikipedia
