According to the clonal selection theory,antigens select lymphocyte clones by:
A) the chemicals secreted by the lymphocytes.
B) the proximity of the lymphocytes to the antigens.
C) the shape of receptors on the lymphocyte's plasma membrane.
D) producing toxins.

Question

Quizplus · Accepted Answer

The clonal selection theory states that lymphocyte clones with receptors that match the shape of an antigen will be selected for proliferation and differentiation. Therefore, the shape of receptors on the lymphocyte's plasma membrane is what ultimately determines which lymphocyte clones are selected by the antigens. Choice A (chemicals secreted by lymphocytes) and choice D (producing toxins) are not part of the clonal selection theory, and choice B (proximity) plays a role in the immune response but is not the main mechanism by which antigens select lymphocyte clones.
