(921) The antigen-binding sites of an antibody molecule are formed from the molecule's variable region. Why are these regions called variable? They can change their shapes on command to fit different antigens. They change their shapes when they bind to an antigen. Their specific shapes are unimportant. They have different shapes on antibodies to different antigens. Their sizes vary considerably from one antibody to another.
