Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Ribosome
Concept: While prokaryotes lack membrane-bound organelles, they still require the essential machinery for life, such as protein synthesis.

Solution: Ribosomes are non-membranous organelles responsible for protein synthesis. Because they are not bound by a membrane, they are universally present in both prokaryotic (70S) and eukaryotic (80S) cells.

Distractor Autopsy: Mitochondria are membrane-bound (absent in prokaryotes). A nucleoid is an irregular region containing DNA in prokaryotes, not an organelle found in eukaryotes.

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.
