Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Ribosome
Concept: The physical structure of the protein-synthesizing machinery is highly distinct from membranous organelles.

Solution: The ribosome is a non-membranous organelle that uniquely consists of two distinct parts: a large subunit and a small subunit, which interlock around mRNA during translation.

Distractor Autopsy: Mitochondria, plastids, and Golgi bodies are continuous, membrane-bound structures, not composed of separate dissociable "subunits".

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.
