Question 1 of 7
Question
Transcription proceeds:
Correct.
Incorrect.
Question
DNA polymerase and RNA polymerase are similar in that:
Correct.
Incorrect.
Question
Occasionally, due to mutation or another issue, mRNAs are produced with premature stop codons. When this occurs, factors of the nonsense-mediated decay (NMD) pathway destabilize the relevant mRNA, repress that mRNA’s translation, promote the degradation of any truncated polypeptides that have been translated, and also feed back to interfere with the transcriptional processing of that mRNA (S. Kervestin and A. Jacobson. 2012. Nat. Rev. Mol. Cell Biol. 13(11):700). This means that:
Correct.
Incorrect.
Question
Energy is required at the onset of transcription to separate the DNA strands and at the termination of transcription when the mRNA is released from polymerase.
Correct.
Incorrect.
Question
Where does transcription happen in a eukaryotic cell?
Correct.
Incorrect.
Question
A mutation in the −10 promoter sequence can lead to:
Correct.
Incorrect.
Question
Which termination mechanism utilizes a separate protein, other than the RNA polymerase, to terminate transcription?
