Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Spherical viruses
Concept:

Viruses are classified structurally based on their capsid symmetry.

Solution:

  • The Poliovirus possesses an icosahedral symmetry, which gives it a roughly spherical appearance under an electron microscope.


Why other options are incorrect:

  • Tadpole shaped: Characteristic of bacteriophages.
  • Rod/Helical shaped: Characteristic of viruses like the Tobacco Mosaic Virus (TMV).

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.
