Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Kary Mullis
Concept:

History and discovery of enzymatic in vitro DNA amplification.

Solution:

Kary Mullis invented the Polymerase Chain Reaction (PCR) in 1983, a revolutionary technique for which he was awarded the Nobel Prize in Chemistry in 1993.

Why other options are incorrect:

  • Frederick Sanger: Developed the chain-termination method for enzymatic DNA sequencing.


  • Allan Maxam: Co-developed the chemical cleavage method for DNA sequencing with Walter Gilbert.


  • Francis Collins: Led the international Human Genome Project consortium.

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.
