Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Singer and Nicolson
Concept: Recognizing key scientists is fundamental in biological history.

Solution: The fluid mosaic model, the universally accepted model for plasma membrane structure, was proposed by S. J. Singer and G. L. Nicolson in 1972.

Distractor Autopsy: Christian de Duve discovered lysosomes. Robert Brown discovered the nucleus. George Palade discovered ribosomes.

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.
