Question
Which of the following viruses has a segmented genome ?
This question was previously asked in
CUET PG 2026 Agri-Business Management Question Paper (25-Mar-2026) (Shift 2)
The correct answer is
Influenza Virus
Virus Genome Segmentation Explained
A segmented genome means a virus's genetic material is split into multiple separate pieces (segments), unlike a single continuous molecule.
Analysis of Viral Genomes
Evaluating the genome structure of the given viruses:
- Tobacco Mosaic Virus (TMV): Features a non-segmented, single-stranded, positive-sense RNA genome ( $ \text{+ssRNA} $ ).
- Rabies Virus: Has a non-segmented, linear, single-stranded, negative-sense RNA genome ( $ \text{-ssRNA} $ ).
- Influenza Virus: Notably possesses a segmented genome, typically comprising eight segments of single-stranded, negative-sense RNA ( $ \text{-ssRNA} $ ). This feature facilitates genetic reassortment.
- Hepatitis B Virus (HBV): Contains a non-segmented, circular, partially double-stranded DNA genome ( $ \text{dsDNA} $ ).
Identifying the Virus with a Segmented Genome
From the options provided, only the Influenza Virus has a segmented genome.
