Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Nucleocapsid
Concept:

The structural anatomy of a virus is composed of fundamental morphological units.

Solution:

  • All viruses contain a genome (either DNA or RNA) and a protective protein coat called a capsid.
  • Together, the nucleic acid core and the surrounding capsid are collectively referred to as the nucleocapsid.


Why other options are incorrect:

  • Envelope: A lipid bilayer outside the nucleocapsid.
  • Capsomeres: Individual protein subunits that make up the capsid.
  • Prions: Infectious proteins lacking nucleic acids entirely.

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.
