Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: 1999
Concept:

Milestones of the Human Genome Project (HGP).

Solution:

Human chromosome 22 was the first human chromosome to be fully sequenced, with its final sequence published in December 1999.

Why other options are incorrect:

  • 1990: The year the Human Genome Project was officially launched internationally.


  • 2003: The year the complete draft of the entire human genome was officially announced.


  • 2005: Subsequent milestone year for other individual chromosome completions (e.g., Chromosome X).

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.
