a. it is larger than cellular DNA
b. It changes very slowly
c. It can be DNA or RNA
d. It can be DNA or protein

Answer 1

C. It can be DNA or RNA

There are different types of viruses. Some are DNA-based and some are RNA based.

For example, papillomavirus (warts) is a DNA virus. HIV is an RNA virus.

Answer 2

Answer: The correct answer is-

c. It can be DNA or RNA.

Viruses can be described as non cellular, microscopic, infective agent that are composed of genetic material ( DNA or RNA), which is surrounded by a protenaceous coat known as viral capsid.

It means that there can be RNA ( ribonucleic acid) and DNA ( deoxyribonucleic acid) based viruses.

Example of DNA virus is human papillomavirus (HPV) and RNA virus is Human immunodefeciency virus ( HIV).

Thus, option c) is the right answer.
