Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Mitochondria
Concept: Some organelles retain evolutionary remnants of a free-living bacterial past.

Solution: Mitochondria (and chloroplasts) are considered semi-autonomous, self-replicating organelles. They possess their own circular DNA and ribosomes, allowing them to divide independently of the cell's main nucleus via a process similar to binary fission.

Distractor Autopsy: The ER, Golgi bodies, and vacuoles are produced and regulated entirely by the main endomembrane system of the cell and cannot replicate themselves.

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.
