1. Define the terms: antigen, hapten, epitope, paratope (slide 43), agretope (slide 40), and immunogen. Describe the differences in how B and T cells and their antigen receptors see antigens and what those differences mean as far as composition of antigens that can be recognized by B and by T cells.

QUESTION 11 How is the immune system able to recognize a limitless number of different antigens and epitopes? While each lymphocyte carries receptors that recognize only one type of epitope, the immune system produces a wide variety of lymphocytes each of which carries unique receptors A genetic "memory" of the pathogens your parents encountered (and their parents and so on) is passed on to each generation, increasing the number of possible responses over time. Each lymphocyte is coated with many...
