Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Prions
Concept:

Pathogens vary dramatically in structural complexity, from multicellular organisms down to mere molecules.

Solution:

  • Prions are the absolute simplest known infectious agents.
  • They are composed exclusively of misfolded proteins and contain absolutely no genetic material (neither DNA nor RNA).


Why other options are incorrect:

  • Viruses: More complex as they contain both nucleic acids and proteins.
  • Fungus/Amoeba: Highly complex eukaryotic organisms.

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.
