Clonal selection clonal selection describes the proliferation of b and t lymphocytes after they have been activated by an antigen. requires the presence and activation of complement. determines the pool of mature leukocytes that will be stimulated by macrophages. requires the activation of natural killer cells.

describes the proliferation of B and T lymphocytes after they have been activated by an antigen.

Explanation:

Clonal selection refers to the process of activation of B and T lymphocytes in which presence of specific antigen in the body stimulates their activation, cell division and differentiation in the specific immune cells carrying the receptors for antigen binding. The process is called clonal selection as it leads to formation of group of identical cells that recognize same specific antigen as the original lymphocyte. Clonal selection in B cells results in formation of plasma cells and memory cells.
