NEET2023Biology
Q.

In which blood corpuscles, the HIV undergoes replication and produces progeny viruses?

  1. A

    T cells

  2. B

    B-lymphocytes

  3. C

    Basophils

  4. D

    Eosinophils

Solution

HIV preferentially binds the CD4 receptor on helper T-lymphocytes (T cells), enters them, replicates, and releases progeny virions that go on to infect more T cells. This progressive depletion of T cells is what causes AIDS.
