Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Genes mutation


Concept:

Biological effects of radiation are divided into Somatic (affecting the direct victim) and Genetic (affecting descendants).

Solution:

  • "Somatic" refers to standard body cells. Damage here results in localized burns, hair loss, cataracts, and eventually cellular cancer.


  • Gene mutation in reproductive germ cells (sperm and ova) does not harm the exposed individual directly. Instead, it creates inheritable deformities in future generations.


  • Therefore, gene mutation is strictly classified as a Genetic effect, not a Somatic effect.


Why other options are incorrect:

Skin burns, loss of hair, and somatic cancer are all textbook examples of direct Somatic damage.

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.
