Which of the following is true about the clonal selection theory?
A) An antigen selects certain B cells to produce a clone of plasma cells.
B) An antibody stimulates the multiplication of B cell antigens against it.
C) T cells select those B cells that should produce antibodies, regardless of antigens.
D) T cells suppress all the B cells except the ones that should multiply and divide.
E) One B cell will give rise to plasma cells that produce antibodies against several antigens.

Question

Quizplus · Accepted Answer

The clonal selection theory states that an antigen selects a specific B cell that possesses a receptor that can bind to that antigen, leading to the activation and proliferation of that B cell into a clone of plasma cells that produce antibodies against that antigen. This is known as clonal selection. Option B is incorrect because antibodies are produced by B cells, not B cell antigens. Option C is incorrect because B cells are selected based on their ability to recognize and bind to antigens, not by T cells. Option D is incorrect because T cells are not responsible for selectively suppressing certain B cells. Option E is incorrect because one B cell can only produce clones of plasma cells that produce antibodies against one specific antigen.
