Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Polysome
Concept: To maximize efficiency, multiple ribosomes translate a single mRNA molecule simultaneously.

Solution: A single mRNA string with multiple ribosomes attached like beads on a thread is called a polysome (or polyribosome). This allows for the rapid production of many identical polypeptide copies.

Distractor Autopsy: A polynucleotide is a chain of nucleic acids (like DNA). A polysaccharide is a carbohydrate chain.

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.
