<prompt> HIV virus has :Single stranded DNASingle stranded RNADouble stranded DNADouble stranded RNA  <response>: Classification of HIV HTLV III Family RetroviridaeSubfamily LentivirusGenome SS RNA positive sense. Virion contain lipoprotein envelope and nucleocapsid is icosahedral in shape. Characteristic feature of retrovirus is presence of reverse transcriptase enzyme. Viral RNA is transcribed by this enzyme first into SS DNA then to ds DNA which gets integrated with host cell. Thus in contrast to central dogma flow of information is RNA DNA RNA
