(b) Transfer of DNA from one bacteria to another bacteria cannot take place.

(c) Virus cannot have both DNA and RNA.

(d) Protists reproduce asexually only.

Answer 1

The correct option is: (c) Virus cannot have both DNA and RNA.

Explanation:

Virus is a nucleoprotein entity which is able to utilise the synthetic machinery of a living cell of another organism for its multiplication which does not involve growth and division. The nucleic acid is either DNA or RNA but never both. DNA containing viruses are called deoxyviruses while RNA containing viruses are termed as riboviruses.
