Question 1
Some statements about viruses are given below.
- A. A virus is a living species.
- B. Viruses have DNA or RNA.
- C. Viruses multiply only inside living cells.
Which of these are true?
The right answer is the one marked above.
B and C. A virus is made of a nucleic acid and a protein coat, and it multiplies only inside a living host cell.
A is wrong: a virus is a non-cellular form that cannot be sorted cleanly into living or non-living, so calling it a "living species" outright will not do.
