MCQs on HIV Life Cycle with Answers

The HIV life cycle begins with attachment to CD4 receptors on host cells, followed by fusion of the viral envelope with the cell membrane. The viral RNA is released and reverse-transcribed into DNA by reverse transcriptase. The viral DNA is transported to the nucleus and integrated into the host genome by integrase. Host cellular machinery transcribes and translates viral genes, producing viral RNA and proteins. These assemble into immature virions at the cell surface. Protease cleaves precursor proteins into functional units, enabling viral maturation. The virus exits the host cell through budding, acquiring a lipid envelope. This process damages the immune system, making the body vulnerable to infections. This MCQs on HIV Life Cycle will help you to study the mechanism of viral replication an pathogensis.
