RNA polymerase - Wikipedia
In molecular biology, RNA polymerase (abbreviated RNAP or RNApol), or more specifically DNA-directed/dependent RNA polymerase (DdRP), is an enzyme that catalyzes the chemical reactions that synthesize RNA from a DNA template.
RNA polymerase I - Wikipedia
RNA polymerase 1 (also known as Pol I) is, in higher eukaryotes, the polymerase that only transcribes ribosomal RNA (but not 5S rRNA, which is synthesized by RNA polymerase III), a type of RNA that accounts for over 50% of the total RNA synthesized in a cell. [1]
RNA polymerase II - Wikipedia
RNA polymerase II (RNAP II and Pol II) is a multiprotein complex that transcribes DNA into precursors of messenger RNA (mRNA) and most small nuclear RNA (snRNA) and microRNA. [1][2] It is one of the three RNAP enzymes found in the nucleus of eukaryotic cells. [3] .
Biochemistry, RNA Polymerase - StatPearls - NCBI Bookshelf
2023年7月17日 · RNA polymerase, abbreviated RNAP and officially known as DNA-directed RNA polymerase, is found in all living organisms as well as many viruses. Present in bacteria, archaea, and even eukaryotes, these RNAPs all share similar protein core …
RNA Polymerase - Definition, Types, Structure, and Functions
2023年11月7日 · RNA polymerase (RNA Pol or RNAP) is the enzyme that synthesizes RNA from a template of DNA, a process known as transcription. It is thus a DNA-dependent RNA polymerase.
10: Transcription: RNA polymerases - Biology LibreTexts
2023年6月20日 · Recall the Central Dogma of molecular biology: DNA is transcribed into RNA, which is translated into protein. We will cover the material in that order, since that is the direction that information flows.
Structure and mechanism of the RNA polymerase II transcription ...
In this review, we detail the structure and mechanism of over a dozen factors that govern Pol II initiation (e.g., TFIID, TFIIH, and Mediator), pausing, and elongation (e.g., DSIF, NELF, PAF, and P-TEFb).
Mechanism of polyadenylation-independent RNA polymerase II
2024年10月18日 · Here we analyze the mechanism of polyadenylation-independent Pol II termination mediated by the yeast Sen1 helicase. Cryo-electron microscopy structures of two pretermination intermediates show...
Structure of the human RNA polymerase I elongation complex
2021年10月20日 · Eukaryotic RNA polymerase I (Pol I) transcribes ribosomal DNA and generates RNA for ribosome synthesis. Pol I accounts for the majority of cellular transcription activity and dysregulation of...
