Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Vector
Concept:

Gene delivery vehicles in human therapeutics.

Solution:

Recombinant gene therapy vectors (such as adenoviruses, lentiviruses, or plasmids) are engineered vehicles used to deliver intact, functional therapeutic genes into target host human cells.

Why other options are incorrect:

  • Antibiotic: Chemical compounds used to treat bacterial infections.


  • Vaccine: Biological agents used to elicit protective immune responses against infectious diseases.


  • Interferon: Antiviral cytokines that modulate host innate immune defenses.

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.
