Vedclass · Answer

(B) $AIDS$ (Acquired Immuno Deficiency Syndrome) is caused by the Human Immunodeficiency Virus $(HIV)$ via sexual or blood-to-blood contact.After entering the human body,the $HIV$ virus attacks and enters the macrophages.Inside the macrophages,the $RNA$ of the virus replicates with the help of the enzyme reverse transcriptase and gives rise to viral $DNA$.Then,this viral $DNA$ incorporates into the host $DNA$ and directs the synthesis of virus particles.At the same time,$HIV$ enters helper $T$-lymphocytes.It replicates and produces viral progeny there.These newly formed progeny viruses are released into the blood,attacking other healthy helper $T$-lymphocytes in the body.As a result,the number of helper $T$-lymphocytes in the body of an infected person decreases progressively,thereby severely weakening the person's immune system.

What is the mechanism by which the $AIDS$ virus causes deficiency of the immune system in an infected person?
