Verified By Collegedunia
Solution and Explanation
Entry: HIV enters host cells (CD4+ Tcells) via surface receptors.
Reverse transcription: Viral RNA is converted into DNA by reverse transcriptase.
Integration: Viral DNA integrates into the host genome via integrase enzyme.
Replication: Host machinery synthesizes viral components.
Assembly and release: New viral particles are assembled and released, infecting other cells.
Progression to AIDS: Gradual destruction of CD4+ cells leads to weakened immunity and opportunistic infections, culminating in AIDS.
