• 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 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 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 — 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

• 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

• Messenger RNA — The life cycle of an mRNA in a eukaryotic cell. RNA is transcribed in the nucleus; processed, it is transported to the cytoplasm and translated by the ribosome. At the end of its life, the mRNA is degraded. Messenger RNA (mRNA) is a molecule of… …   Wikipedia

• Transfer RNA — The interaction of tRNA and mRNA in protein synthesis tRNA Identifiers Symbol tRNA …   Wikipedia

• Non-coding RNA — A non coding RNA (ncRNA) is a functional RNA molecule that is not translated into a protein. Less frequently used synonyms are non protein coding RNA (npcRNA), non messenger RNA (nmRNA) and functional RNA (fRNA). The term small RNA (sRNA) is… …   Wikipedia

• Guide RNA — is the RNA that guides the insertion of uridines into mRNAs in trypanosomes in a process known as RNA editing. These are encoded at distant regions of the kinetoplast genome. The 5 end of a gRNA hybridizes to a short region of an unedited pre… …   Wikipedia

• Cell nucleus — HeLa cells stained for the cell nucleus DNA with the Blue Hoechst dye. The central and rightmost cell are in interphase, thus their entire nuclei are labeled. On the left, a cell is going through mitosis and its DNA has condensed ready for… …   Wikipedia

• Alternative splicing — produces two protein isoforms. Alternative splicing (or differential splicing) is a process by which the exons of the RNA produced by transcription of a gene (a primary gene transcript or pre mRNA) are reconnected in multiple ways during RNA… …   Wikipedia
