Propolis Cognitive Error Autopsy

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

Diagnostic molecular probes in pathogen detection.

Solution:

DNA/RNA probes hybridize specifically to target genomic sequences of viruses, bacteria, or genetic mutations, functioning as crucial molecular diagnostic tools for infectious and genetic diseases.

Why other options are incorrect:

  • carrier in gene cloning experiments: Cloning vectors (e.g., plasmids, bacteriophages) transfer recombinant DNA, not diagnostic probes.


  • cementing material in somatic cell hybridization: Polyethylene glycol (PEG) acts as the chemical fusogen in cell fusion.


  • carrier or vector in gene therapy: Modified viral delivery vectors transport therapeutic genes into host target cells.

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.
