Step-by-step solution
The human immunodeficiency virus (HIV) causes AIDS (acquired immunodeficiency syndrome) and interferes with the body's ability to fight infection. The HIV infects macrophages and T H cells and upon infection, it inactivates these cells and hence, suppresses the immune system. The structure of the virus is such that it is enveloped with a viral envelope (consists of a bilipid layer and proteins) inside which two identical molecules of single-stranded RNA molecules and two molecules of reverse transcriptase are p
