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 Both (a) and (b) By rearrangements of the DNA encoding the variable regions of the heavy and light chains By the combination of different heavy and light chains that form the antigen binding site Antibody proteins can physically change their shape to bind different epitopes Both (a) and (b) By rearrangements of the DNA encoding the variable regions of the heavy and light chains By the combination of different heavy and light chains that form the antigen binding site ANSWER DOWNLOAD EXAMIANS APP
