Which of the following infectious agents is classified as a retrovirus_____________?
Show answer Hide answer
Answer: A. Immunodeficiency virus
Explanation
Human immunodeficiency virus belongs to the retrovirus family characterized by reverse transcription. Viral RNA genomes are converted into double-stranded DNA inside host cells by reverse transcriptase. Option A correctly classifies the immunodeficiency virus among viral taxonomic groups. Retroviruses possess enveloped virions containing two copies of single-stranded RNA molecules. Integration of viral DNA into host chromosomes establishes lifelong chronic infections. Lentivirus genus members cause slow progressive diseases involving immune system depletion.
Antiretroviral therapies specifically target reverse transcriptase and other retroviral enzymes. Diagnosing HIV infections relies on detecting viral antibodies, antigens, or RNA molecules. Retroviral research has driven major advancements in molecular biology and gene therapy. Influenza viruses are orthomyxoviruses possessing segmented negative-sense single-stranded RNA genomes. Polioviruses are enteroviruses classified within the picornavirus family with positive-sense RNA. Hepatitis viruses comprise diverse taxonomic families like hepadnaviruses and flaviviruses.
