Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Non-enveloped viruses
Concept:

The outermost layer of a virion dictates its categorization regarding an envelope.

Solution:

  • Viruses that consist only of a nucleocapsid (nucleic acid + protein capsid) and lack an outer lipid bilayer are termed naked viruses or non-enveloped viruses.


Why other options are incorrect:

  • Enveloped viruses: Have an outer lipid layer.
  • Viroids/Prions: These are subviral particles (naked RNA and infectious proteins, respectively), not classified as naked "viruses" in standard taxonomy.

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.
