Retroviruses integrate the DNA produced by reverse transcription in to the host genome as being a provirus to be a Element of the replication course of action; pararetroviruses don't, While integrated genome copies of In particular plant pararetroviruses can give rise to infectious virus.[81] They are really prone to antiviral medicine that inhibit the reverse transcriptase enzyme, e.g. zidovudine and lamivudine. An example of the initial sort is HIV, that's a retrovirus. Samples of the next type are definitely the Hepadnaviridae, which incorporates Hepatitis B virus.[26]: 88–89

A virus has either a DNA or an RNA genome and is known as a DNA virus or an RNA virus, respectively. Most viruses have RNA genomes. Plant viruses have a tendency to acquire one-stranded RNA genomes and bacteriophages have a tendency to own double-stranded DNA genomes.[26]: ninety six–99
