Question

Which of the following correctly matches a virus with its type of nucleic acid?

• A. Poliovirus -- double-stranded DNA
• B. Influenza virus -- negative-sense single-stranded RNA
• C. Adenovirus -- single-stranded RNA
• D. HIV -- single-stranded DNA

Hint:

Remember the important viral genomes: \[ \boxed{ \begin{aligned} \text{Poliovirus} &\rightarrow (+)\text{ssRNA} \text{Influenza virus} &\rightarrow (-)\text{ssRNA} \text{Adenovirus} &\rightarrow \text{dsDNA} \text{HIV} &\rightarrow (+)\text{ssRNA (Retrovirus)} \end{aligned} } \]

Answer 1

The Correct Option is B

Step 1: Recall the nucleic acid present in common viruses. Some important viral genomes are \[ \begin{aligned} \text{Poliovirus} &\rightarrow \text{Positive-sense single-stranded RNA}, \text{Influenza virus} &\rightarrow \text{Negative-sense single-stranded RNA}, \text{Adenovirus} &\rightarrow \text{Double-stranded DNA}, \text{HIV} &\rightarrow \text{Positive-sense single-stranded RNA (Retrovirus)}. \end{aligned} \]

Step 2: Identify the correct match. Among the given options, \[ \boxed{ \text{Influenza virus -- negative-sense single-stranded RNA} } \] is the correct combination. Therefore, \[ \boxed{(B)} \] is the correct answer.
