Detailed explanation-1: -All viruses have genetic material (a genome) made of nucleic acid. You, like all other cell-based life, use DNA as your genetic material. Viruses, on the other hand, may use either RNA or DNA, both of which are types of nucleic acid.
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: -Leuko virus is a retrovirus also called as RNA-DNA virus. These virus possess reverse transcriptase. This enzyme builds DNA over RNA genome. This phenomenon is called, reverse transcription or teminism.
Detailed explanation-4: -Viruses contain genetic material which is either RNA or DNA. No virus contains both RNA and DNA. Further, this genetic material is of 4 types double-stranded DNA, single-stranded DNA, double-stranded RNA, single-stranded RNA.
