Question
Which of the following explains why AZT does not substitute for thymine in non-virus nucleic acids? A. It is specific to reverse transcriptases B. Mammalian polymerases have more advanced proofreading functions which cleave out AZT C. Mammalian polymerases have more advanced proofreading functions which cleave out AZT D. In transcription, uracil is used instead of thymine, so this process cannot affect human mRNA On a particular length of DNA, the sequence TATAAAGCTA appears. What will result after RNA Pol II activity? A. The RNA sequence: AUAUUUCGAU B. The RNA sequence: ATATTTCGAT C. The RNA sequence: CGUA D. No transcription will occur on this segment All of the following enzymes function in the unwinding of DNA during replication EXCEPT: A. Single-strand binding protein B. Helicase C. Primase D.
