Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Cell membrane
Concept:

Viral taxonomy utilizes inherent structural and biological properties of the virus.

Solution:

  • Viruses are completely acellular. They entirely lack a cell membrane, cytoplasm, and organelles.
  • Because a cell membrane is absent in all viruses, it cannot be used as a criterion for their classification.


Why other options are incorrect:

  • Morphology, Envelope presence, Host specificity: These are the primary criteria used universally by virologists to classify viral families.

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.
