(A) $AIDS$ (Acquired Immuno Deficiency Syndrome) is caused by the Human Immunodeficiency Virus $(HIV)$.After entering the body,the virus enters macrophages where $RNA$ genome of the virus replicates to form viral $DNA$ with the help of the enzyme reverse transcriptase.This viral $DNA$ gets incorporated into the host cell's $DNA$ and directs the infected cells to produce virus particles.The macrophages continue to produce virus and in this way act like an $HIV$ factory.Simultaneously,$HIV$ enters into helper $T-$ lymphocytes ($T_H$ cells),replicates and produces progeny viruses.The progeny viruses released in the blood attack other helper $T-$ lymphocytes.This is repeated leading to a progressive decrease in the number of helper $T-$ lymphocytes in the body of the infected person.
