Clonal Selection Implies That

Question

Clonal selection implies that
A)brothers and sisters have similar immune responses.
B)antigens increase mitosis in specific lymphocytes.
C)only certain cells can produce interferon.
D)a B cell has multiple types of antigen receptors.
E)the body selects which antigens it will respond to.

Accepted Answer

Clonal selection refers to the process by which specific lymphocytes (B cells and T cells) are selected and activated in response to a specific antigen. When an antigen enters the body, it stimulates the proliferation of lymphocytes that have specific receptors that are complementary to the antigen. This results in the production of many identical copies, or clones, of the lymphocyte that can recognize and bind to the antigen. Therefore, option B (antigens increase mitosis in specific lymphocytes) is the best choice as it describes the process of clonal selection.
