Question

Which one of the following animal viruses contains double stranded RNA as genetic material?

• A. Influenza virus
• B. Rous sarcoma virus
• C. Polio virus
• D. Reovirus

Hint:

Reoviruses are important examples of double-stranded RNA viruses, whereas Influenza, Polio, and Retroviruses contain single-stranded RNA genomes.

Answer 1

The Correct Option is D

Step 1: What we are after.
We want the virus whose genome is double stranded RNA.

Step 2: Sort the RNA viruses.
Influenza carries single stranded negative sense RNA. Polio carries single stranded positive sense RNA. Rous sarcoma virus is a retrovirus with single stranded RNA and reverse transcriptase.

Step 3: Find the dsRNA one.
Reovirus is the standout, famous for a segmented double stranded RNA genome.

Step 4: Answer.
So the dsRNA virus is Reovirus. \[ \boxed{\text{Reovirus}} \]
