Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Gene for antigen of pathogen
Concept:

Recombinant gene expression of protective antigens.

Solution:

Recombinant DNA technology isolates and clones the specific gene encoding a surface antigen of a pathogen, allowing host cells to express pure antigens for safe vaccine formulation.

Why other options are incorrect:

  • Gene for receptor of the patient: Cloning human receptors does not stimulate active host immunity against foreign micro-organisms.


  • Gene for antigen of patient: Patient self-antigens are tolerated by the immune system and do not confer protection against pathogens.


  • Gene for antibody of patient: Cloning antibody genes produces passive immunoglobulins rather than active subunit vaccines.

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.
