• 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 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 — 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

• Methylation — In the chemical sciences, methylation denotes the addition of a methyl group to a substrate or the substitution of an atom or group by a methyl group. Methylation is a form of alkylation with, to be specific, a methyl group, rather than a larger… …   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

• Small nucleolar RNA snoR60 — is a non coding RNA (ncRNA) molecule which functions in the modification of other small nuclear RNAs (snRNAs). This type of modifiying RNA is usually located in the nucleolus of the eukaryotic cell which is a major site of snRNA biogenesis. It is …   Wikipedia

• DNA methylation — Illustration of a DNA molecule that is methylated at the two center cytosines. DNA methylation plays an important role for epigenetic gene regulation in development and disease. DNA methylation is a biochemical process that is important for… …   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

• Small nucleolar RNA SNORD15 — SNORD15 (also known as U15) is a non coding RNA (ncRNA) molecule which functions in the modification of other small nuclear RNAs (snRNAs). This type of modifying RNA is usually located in the nucleolus of the eukaryotic cell which is a major site …   Wikipedia
