Ribosomal RNA — (rRNA) is the central component of the ribosome, the protein manufacturing machinery of all living cells. The function of the rRNA is to provide a mechanism for decoding mRNA into amino acids and to interact with the tRNAs during translation by… … Wikipedia
Ribosomal RNA — A molecular component of a ribosome, the cell s essential protein factory. Ribosomal RNA (rRNA) fabricates polypeptides (assemblies of amino acids that make up proteins). A tiny particulate structure located in the cytoplasm of the cell (outside… … Medical dictionary
5.8S ribosomal RNA — (5.8S rRNA) is a component of the large subunit of the eukaryotic ribosome. It is transcribed by RNA polymerase I as part of the 45S precursor that also contains 18S and 28S rRNA. Functionally, it is thought that 5.8S rRNA may be involved 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
Ribosomal DNA — The gene segment of eukaryotic rDNA contains 18S, 5.8S, and 28S tracts and forms a tandem repetitive cluster; the 5S rDNA is coded separately. NTS, nontranscribed spacer, ETS, external transcribed spacer, ITS, internal transcribed spacers 1 and 2 … 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 polymerase I — An impressive 50%+ of all RNA synthesis in a cell is accounted for by the transcription of rRNA. Eukaryotic cells have evolved a polymerase strictly dedicated to this pursuit.RNA polymerase I (also called Pol I) transcribes DNA to synthesize rRNA … Wikipedia
Small nucleolar RNA SNORD22 — snoRNA U22 (also known as SNORD22) 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… … Wikipedia
Small nucleolar RNA SNORD16 — snoRNA U16 (also known as SNORD16) 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… … Wikipedia
Small nucleolar RNA SNORD43 — snoRNA U43 (also known as SNORD43) 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… … Wikipedia
