Question

Quizplus · Accepted Answer

The variable segment of an antibody is the region that is specifically tailored to fit a specific antigen. This region is highly variable, allowing for the recognition of a vast number of different antigens. The constant segment, heavy chain, and hapten are all related to different aspects of antibody structure and function, but do not play a role in the specific recognition of antigens. A bond could refer to many different types of chemical bonds, and is not specific to antibodies.
