Answer:D

Explanation:

D) They have both DNA and RNA. This option is incorrect.

Viruses are absolute parasites on living cells, they lack cells and are very good in replicating themselves. Alfred Hershey proved that their genetic material is made up of nucleic acids and not proteins. Though all viruses contain nucleic acid, which is either DNA (deoxyribonucleotides) or RNA (ribonucleotides) but no virus contains both RNA and DNA. Their genetic material are encased in a protein coat.
