Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Chromatin
Concept: The word "chromosome" literally translates to "colored body" (chroma = color, soma = body).

Solution: The nucleus stains deeply with basic biological dyes (like hematoxylin or methylene blue) due to the high concentration of negatively charged nucleic acids in the chromatin (DNA wrapped around histone proteins).

Distractor Autopsy: Lipids do not bind basic dyes well. Thylakoids are in chloroplasts. Metal ions are not the primary target of nuclear stains.

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.
