Q.

In which blood corpuscles, the HIV undergoes replication and produces progeny viruses            [2023]
1 Basophils  
2 Eosinophils  
3 TH Cells  
4 B-lymphocytes  

Ans.

(3)

HIV enters into helper T-lymphocytes (TH), 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 number of helper T-lymphocytes in the body of infected person.
