Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Can replicate on their own
Concept:

Viruses are obligate intracellular parasites entirely dependent on host machinery.

Solution:

  • The statement "Can replicate on their own" is fundamentally false.
  • Viruses possess zero metabolic enzymes and lack ribosomes. They must invade a host cell to copy their genome and synthesize their capsids.


Why other options are incorrect:

  • Contain DNA, Can infect bacteria, Have sub-cellular structure: These are all factual statements. Some viruses contain DNA, bacteriophages infect bacteria, and they are sub-cellular (acellular) entities.

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.
