|
False
|
|
Either A or B
|
|
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.
