Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: DNA and proteins
Concept: To fit two meters of DNA into a microscopic nucleus, it must be intricately spooled around structural supports.

Solution: A eukaryotic chromosome is a complex of nucleic acid and protein called chromatin. It is composed primarily of a long, continuous molecule of DNA tightly wrapped around octamers of basic histone proteins.

Distractor Autopsy: RNA is transcribed from DNA but does not form the permanent structural backbone of the chromosome. Lipids are not found in chromosomes.

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.
