Answer:
- HIV: positive single-stranded RNA (+ssRNA) retrovirus (family Retroviridae)
- Influenza virus: negative single-stranded RNA (-ssRNA) virus (family Orthomyxoviridae)
Step-by-step explanation:
The human immunodeficiency virus (HIV) is a single-stranded RNA (+ssRNA) virus. These viruses (+ssRNA) encode an RNA replicase that acts as messenger RNA (mRNA) to be directly translated into viral proteins, while in the replication cycle of negative ssRNA viruses they first encode a negative-sense sequence which is then used as a template to generate more positive-sense viral genomes. HIV-1 and HIV-2 are well-known retroviruses (family Retroviridae, genus Lentivirus) which encode a DNA intermediate that is integrated into the host genome cells. Unlike HIV viruses, the Influenza virus does not integrate into the host genome cells.
