According to the Clonal Selection Theory

Question

According to the clonal selection theory
A)antibodies are modified, at the time of antigen exposure, to specifically react with the antigen.
B)self-reactive T cells are killed in the thymus.
C)B cells producing autoantibodies are eliminated in the thymus.
D)each B cell is already programmed to produce a specific antibody.
E)self-reactive T cells are killed in the thymus AND B cells producing autoantibodies are eliminated in the thymus.

Accepted Answer

The clonal selection theory states that each B cell is already programmed to produce a specific antibody. When an antigen binds to the B cell, the B cell is then activated and undergoes clonal expansion, producing more cells that produce that specific antibody. This theory does not address the elimination of self-reactive T cells or B cells producing autoantibodies.
