Immune System Numerous antibodies can be prepared, against one antigen, each binds to unique epitopes. How is this antibody diversity generated? Antibody proteins can physically change their shape to bind different epitopes By the combination of different heavy and light chains that form the antigen binding site By rearrangements of the DNA encoding the variable regions of the heavy and light chains Both (a) and (b) Antibody proteins can physically change their shape to bind different epitopes By the combination of different heavy and light chains that form the antigen binding site By rearrangements of the DNA encoding the variable regions of the heavy and light chains Both (a) and (b) ANSWER DOWNLOAD EXAMIANS APP
