Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Centromere
Concept: Accurate segregation of chromosomes requires a strong, centralized physical anchor point for motor proteins.

Solution: During mitosis and meiosis, spindle fibers (microtubules) attach to a specialized protein complex called the kinetochore, which is assembled at the highly constricted region of the chromosome known as the centromere.

Distractor Autopsy: Telomeres are the protective caps at the ends of chromosomes. Histones are the spools for DNA. The nucleolus is a nuclear organelle.

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.
