It was proposed that template DNA binds in the cleft. In molecular biology, RNA polymerase (abbreviated RNAP or RNApol, and officially DNA-directed RNA polymerase), is an enzyme that synthesizes RNA from a DNA template. The reaction that this enzyme catalyzes for is: (RNA)n + Ribonucleoside Triphosphate ->/<- (RNA… Both DNA polymerase 1 and 3 possess … it is enzymes that copies DNA To rRNA IT is a type of RNA that almost account for over 50% of RNA synthesis It synthesize RNA for large subunit of ribosomes Molecular mass is of around 500KD The Rate of transcription by it is slower than RNA polymerase II it is only 20 nucleotide Termination by it involves DNA … Dinosaur Simulator Pvp Tier List, Foam Pipe Wrap, Wardrobe Sliding Doors Design, Craftsman T2400 Riding Lawn Mower Manual, Only The Brave Foundation, Florence Price: Dances In The Canebrakes, Chandigarh Weekly Express, Jellycat White Elf, olvasson tovább...
