Question

In viruses, the nucleic acid is

• A. DNA
• B. RNA
• C. Both A or B
• D. Either A or B

Answer 1

The correct option is D Either A or B

A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses contain the genetic material which can be DNA or RNA but not the both. The genetic material is enclosed by a capsid. Based on genetic material viruses can be classified into DNA viruses and RNA viruses. The genetic material can be single-stranded or double-stranded. The single-stranded genetic material can be either a positive sense or negative sense.

So, the correct answer is 'Either A or B'.
