Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Retrovirus
Concept:

Viral classification relies on the nature of the genome and its replication strategy within the host cell.

Solution:

  • The Human Immunodeficiency Virus (HIV) carries RNA as its genetic material.
  • It is classified as a retrovirus because it utilizes the enzyme reverse transcriptase to reverse the standard flow of genetic information, synthesizing DNA from its RNA genome.


Why other options are incorrect:

  • Flavivirus, Novavirus, Tetravirus: These are distinct viral families or genera with different genomic structures and replication mechanisms (e.g., Flaviviruses include Dengue and Zika, but they do not use reverse transcription to integrate into the host genome).

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.
