  • 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 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 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
