Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Inside the capsid
Concept:

Retroviruses must physically carry their replication enzymes into the host cell because the host lacks RNA-dependent DNA synthesis machinery.

Solution:

  • HIV packages its three essential replication enzymes (reverse transcriptase, integrase, and protease) directly inside the capsid, alongside its viral RNA genome.
  • This ensures that the moment the capsid uncoats in the host cytoplasm, the enzymes are immediately available to begin reverse transcription.


Why other options are incorrect:

  • In the protein spikes / Outside the capsid: Enzymes placed outside the protective core would be unstable and useless during the intracellular replication phase. Spikes are strictly for attachment.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
