Clonal selection and differentiation of B cells activated by antigen exposure leads to the production of ________.
A) large quantities of the antigen initially recognised
B) vast numbers of B cells with random antigen-recognition receptors
C) long-lived erythrocytes that can later secrete antibodies for the antigen
D) short-lived plasma cells that secrete antibodies for the antigen

Question

Quizplus · Accepted Answer

Clonal selection and differentiation of B cells activated by antigen exposure leads to the production of short-lived plasma cells that secrete antibodies for the antigen. These plasma cells produce a large quantity of antibodies specific to the antigen and are responsible for the initial defense against the invading pathogen.
