Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
All viruses have both types of nucleic acid
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Any particular virus will only have one type of nucleic acid genome, however, and so viruses are not encountered that have both ssDNA and ssRNA genomes, for example.

Detailed explanation-2: -Viruses are smaller and simpler in construction than unicellular microorganisms, and they contain only one type of nucleic acid-either DNA or RNA-never both.

Detailed explanation-3: -Viruses contain nucleic acid as RNA or DNA. These molecules possess all the genetic information of the virus.

Detailed explanation-4: -Nucleic acid is also present in the bacteria in the form of a nucleoid. Thus, bacteria and viruses both contain nucleic acids in their genetic material.
