Questions and Answers

What type of antibiotic are DNA polymerase inhibitors?

  • Antibacterials
  • Antifungals
  • Antivirals (correct)
  • Antiprotozoals

Which of the following is NOT a mechanism of action for DNA polymerase inhibitors?

  • They are incorporated into DNA during normal replication.
  • They directly bind and inhibit the viral DNA polymerase enzyme. (correct)
  • The inhibitors are modified so that they do not permit added nucleotides to be added to that chain as it replicates.
  • The lack of 3' hydroxyl group prevents the incorporation of the next nucleotide, causing chain termination.

What type of antibiotic are reverse transcription inhibitors, and what viruses do they target?

  • Antivirals that target retroviruses like HIV (correct)
  • Antiprotozoals that target parasitic infections
  • Antifungals that target yeast and mold
  • Antibacterials that target Gram-positive bacteria
