Question

Question 10 3 During an infection: The same type of antibody is produced by many B cells One B cell can make more than two different antibodies, provided that they recognize the same antigen Each B-cell produces antibodies to a variety of antigens A variety of antibodies are produced by many B cells, but B cell only produces one type of antibody Question 11 3 pts How are the development of T cells and B cells different? Only T cells require antigen receptor binding to MHC molecules during their development Only T cells with with antigen receptors that recognize self antigens undergo apoptosis. Only B cell antigen receptors are generated through rearrangements in their receptor-encoding genes Only B cells lacking productive rearrangements of their receptor genes undergo apoptosis

Answer 1

Q. 10.

D)

Antigens contain different epitopes on their surface which is recognised by the naive B cells and the B cells become matured. Now, when each of these epitopes are recognised, the B cell starts producing antibodies against only that epitope. By this way different B cells which recognise a single epitope each produce different antibodies against different epitopes of a single antigen but each B cell will produce only a single type of antibodies which is specific for a single epitope.
