Some viruses contain RNA; these are known as retroviruses. Others contain DNA.
yes
Viruses contain either DNA or RNA.
The RNA viruses that contain reverse transcriptases are collectively called retroviruses among which are: HIV, human immunodeficiency virus (AIDS); RNA tumor viruses (leukemia)
They need either DNA or RNA.
Yes. Although not both together, a virus contains a nucleic acid, either single stranded or double stranded DNA or RNA.
Retrovirus utilize an enzyme to produce DNA from their RNA, which can be inserted into the host genome.
yes
Yes. Viruses contain a protein coat called a capsid. Inside this capsid will be DNA or RNA but never both. Viruses that contain RNA are called retroviruses. They also contain the enzyme reverse transcriptase that allows them to convert RNA into double-stranded DNA once it infects a cell.
They contain either DNA or RNA which contain genes for making more of the same viruses.
Infuenza Virus Contain Both DNA and RNA. No other Virus show such characteristics.
Viruses do not contain DNA or RNA . . . they 'steal' those molecules from their host living cell.
NO, RNA is almost always single stranded. The only exception is in certain viruses that contain double-stranded RNA.
