举一反三
- Using the DNA template in a process called _______ RNA is synthesized utilizing which enzyme? A: translation, RNA polymerase B: transcription, DNA polymerase C: transcription, RNA polymerase D: replication, DNA polymerase
- 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.
- Reverse transcriptase catalyses: A: Synthesis of RNA from DNA B: Breakdown of RNA C: Synthesis of DNA from RNA D: Breakdown of DNA
- RNA polymerase: () A: binds tightly to a region of DNA thousands of base pairs away from<br/>the DNA to be transcribed. B: can synthesize RNA chains without a primer. C: has a subunit called λ (lambda), which acts as a proofreading<br/>ribonuclease. D: separates DNA strands throughout a long region of DNA (up to<br/>thousands of base pairs), then copies one of them. E: synthesizes RNA chains in the 3' →direction.
- If the DNA strand shown below is used as a template for RNA polymerase, what would be the sequence of the resultant mRNA following transcription? 5'-CATTCCATAGCATGT-3'
