Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: diagnostic tools of infectious diseases
Concept:

Diagnostic identification via nucleic acid hybridization.

Solution:

Probes utilize complementary base pairing to detect signature viral or bacterial sequences in clinical samples, establishing their role as diagnostic tools for infectious diseases.

Why other options are incorrect:

  • carrier in gene cloning experiments: DNA vectors like plasmids carry recombinant genes, not diagnostic probes.


  • cementing material in somatic cell hybridization: Chemical fusogens like PEG facilitate membrane fusion between cells.


  • carrier or vector in gene therapy: Engineered viruses act as delivery vehicles for gene replacement therapy.

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.
