Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: They are tolerant to antibodies
Concept:

An envelope provides stealth but makes the virion physically fragile and immunologically detectable.

Solution:

  • Enveloped viruses are highly antigenic and are NOT tolerant to antibodies.
  • Antibodies readily bind to the viral glycoproteins protruding from the envelope, neutralizing the virus effectively.


Why other options are incorrect:

  • Short survival, derived from host, sensitive to sunlight: These are accurate characteristics of enveloped viruses, as the lipid bilayer degrades easily in external 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.
