The rabies virus is a negative-sense, non-segmented, single-stranded RNA virus measuring approximately 60 nm × 180 nm. It is composed of an internal protein core or nucleocapsid, containing the nucleic acid, and an outer envelope, a lipid-containing bilayer covered with transmembrane glycoprotein spikes. Hence, Option A.

Overview of the Rabies Virus
The rabies virus is a significant pathogen known for causing rabies, a lethal disease primarily transmitted through the bite of infected animals. Understanding its genetic composition is crucial for diagnosing and developing treatments.
Genetic Material of the Rabies Virus
- The rabies virus is classified as a single-stranded RNA virus.
- Its genetic material is composed of negative-sense single-stranded RNA (S.S. RNA).
Why Option 'A' is Correct
- Single-Stranded RNA (S.S. RNA): The rabies virus contains one strand of RNA that serves as its genetic blueprint. This allows it to replicate efficiently within a host cell.
- Negative-Sense RNA: The RNA of the rabies virus is negative-sense, meaning it must be converted into a positive-sense RNA by the viral RNA polymerase before it can be translated into proteins.
Additional Information
- Structure: Rabies virus belongs to the Lyssavirus genus and is enveloped, giving it stability and aiding in host cell entry.
- Replication: Once inside a host cell, the viral RNA is transcribed and replicated, leading to the production of viral proteins and new virions.
Conclusion
In summary, the rabies virus has a single-stranded RNA genome, making option 'A' the correct answer. Understanding the genetic composition of the rabies virus is essential for developing effective vaccines and treatments.
