Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Detecting specific tumor markers in samples
Concept:

Diagnostic application of monoclonal antibodies in oncology.

Solution:

Monoclonal antibodies are engineered to bind specifically to tumor-associated antigens (tumor markers) present on cancerous cells or shed into body fluids, facilitating early cancer detection and staging.

Why other options are incorrect:

  • Replacing damaged tissue: Tissue replacement requires stem cell therapies or bioengineered tissue constructs.


  • Changing the genetic code of cancer cells: Altering genetic sequences requires genomic modification systems like CRISPR, not antibodies.


  • Killing healthy cells to reduce tumor spread: Diagnostic methods target tumor markers non-destructively and do not aim to kill healthy host 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.
