Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Capsid
Concept:

Viral architecture consists of a nucleic acid interior and a protective protein exterior.

Solution:

  • The precise virological term for the protein coat that encloses and protects the viral genetic material is the capsid.


Why other options are incorrect:

  • Viroid/Phage: These describe types of infectious agents, not structural layers.
  • DNA sheath: Not a standard virological term; bacteriophages have a tail sheath, but it surrounds the tail tube, not the main genomic head.

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.
