Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Vector
Concept:

Delivery vehicles in human recombinant gene therapy.

Solution:

A molecular vector (such as a engineered retroviral genome, adenovirus, or recombinant plasmid) is the required transport vehicle engineered to carry and insert therapeutic genes into host target cells.

Why other options are incorrect:

  • Antibiotic: Antimicrobial chemical compounds that inhibit or kill bacterial cells; they cannot insert therapeutic eukaryotic genes.


  • Vaccine: Biological preparations that stimulate active acquired immunity against pathogens.


  • Interferon: Signaling proteins (cytokines) produced by host cells in response to viral infections.

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.
