University of Minnesota, Morris - BIOLOGY 222 CH15 1)The immune response is directed against an entire molecule

2.         All antigens are immunogens.              

3.         Antibody molecules are very rigid in structure.           

4.         Antibody and antigen are held to one another by covalent bonds.     

5.         IgA is the most abundant immunoglobulin made by the body.           

6.         Gene rearrangement is responsible for the generation of the various antibody molecules.             

7.         T cells are responsible for directly manufacturing antibodies.           

8.         T cell receptors are identical to antibodies.     

9.         T cell independent antigens lead to a memory response.
