Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Living cells
Concept:

Viruses are defined by their obligate intracellular parasitic nature.

Solution:

  • Viruses lack the independent metabolic machinery required for reproduction.
  • They must infect a living cell (host) to hijack its biosynthetic machinery (ribosomes, enzymes) to replicate.


Why other options are incorrect:

  • Animal/Bacterial cells: These are specific types of living cells, but viruses infect a wide variety of living cells (plants, fungi, etc.), making "Living cells" the most comprehensive and correct answer.
  • Non-living cells: Viruses cannot replicate in dead or non-living environments.

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.
