WebRNA polymerase works by catalyzing the nucleophilic attack of 3’ OH of RNA to the alpha phosphate of a complementary NTP molecule to create a growing strand of RNA from the template strand of DNA. Furthermore, RNA polymerase also displays exonuclease activities, meaning that if improper base pairing is detected, it can cut out the incorrect … Web7 jan. 1997 · In eukaryotes, RNA polymerase II transcribes messenger RNAs and several small nuclear RNAs. Like RNA polymerases I and III, polymerase II cannot act alone. Instead, general initiation factors [transcription factor (TF) IIB, TFIID, TFIIE, TFIIF, and TFIIH] assemble on promoter DNA with polymerase II, creating a large … WebRNA polymerase, as a complex protein subunit, controls the transcription process, in which information stored in a DNA molecule is copied into a new messenger RNA molecule. ...
