Question

The genetic material of rabies virus is
A. Double stranded RNA
B. Single stranded RNA
C. Double stranded DNA
D. Single stranded DNA

Answer 1

DNA and RNA both are genetic material. DNA is double stranded and RNA is single stranded in structure. Rabies is a virus which contains RNA.

Complete answer:
Rabies is a virus that can cause rabies disease in humans.
It is a single stranded RNA virus.
The genome of rabies virus encodes 5 proteins designated as N, P, M, G and L.
The most common path for rabies transmission is the contact of saliva of animals.
Human saliva cannot transmit rabies transmission.
Rabies virus has a large range of hosts – from reptiles to mammals, from insects to birds.
So, the correct answer is option B. Single stranded RNA.

Additional information:
The rabies virus has a bullet like structure and has a length of about 180 nm.
One end of the surface of the virus is conical or round shaped and the other end of the surface is concave or planar shaped.
The rabies genome that is encoded by 5 genes is – N for nucleoprotein, P for phosphoprotein, M for matrix protein, G for glycoprotein and L for polymerase.
The single helix RNA is present on the core region of the virion.
Symptoms of this disease include fever, discomfort, headache, anxiety, cerebral dysfunction etc.

Note: Rabies is a single stranded RNA virus from the Rhabdoviridae family. The most common species from this family is Rabies lyssavirus that causes infection to animals including humans.
