Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Proteins, Ribosomes and small circular DNA
Concept: Chloroplasts are semi-autonomous organelles equipped to synthesize some of their own proteins.

Solution: In accordance with the endosymbiotic theory, chloroplasts contain all the necessary machinery for basic autonomy: small circular DNA, 70S ribosomes, and the resulting synthesized proteins.

Distractor Autopsy: Selecting "only" for any single component ignores the integrated biochemical system required for the chloroplast to function as a semi-autonomous unit.

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.
