- The correct statement about RNA polymerase and DNA polymerase is (1 point) A: Synthesis of polynucleotide chain using nucleoside diphosphate B: RNA polymerase requires primers and bases are added at the 5′-end of the extended polynucleotide chain C: DNA polymerase can only synthesize DNA using RNA as a template D: DNA polymerase can add nucleotides on both ends of a chain at the same time E: , DNA polymerase and RNA polymerase can catalyze the formation of 3',5'-phosphodiester bond
- Which of the following descriptions about DNA and RNA polymerase are correct: A: RNA polymerase synthesize RNA chain using nucleoside diphosphate instead of nucleoside triphosphates. B: RNA polymerase can initiate transcription without a primer, and nucleotides are added to 5’ end of the growing RNA chain. C: RNA polymerase can add nucleotides in both 3’ or 5’ end of RNA chain. D: Both RNA polymerase and DNA polymerase can only add nucleotides to 3’ end of the polynucleotides.
- In the following descriptions of DNA polymerase and RNA polymerase, the error is: ( ) A: RNA polymerase requires primers B: DNA polymerase can synthesize DNA using RNA as a template C: The extension direction of the new chain catalyzed by both enzymes is 5'-3'. D: RNA polymerase uses NDP as raw material.
- There is only One RNA polymerase which can transcribe all types of RNA in bacterial cells. Howeve, in animal nucleus there are three different RNA polymerases that transcribe different types of RNA
