Question

Quizplus · Accepted Answer

The variable region of the antibody binds to the antigen. This region is responsible for the specificity of the antibody as it contains unique amino acid sequences that allow it to recognize and bind to a specific antigen. The constant region, heavy chain, and light chain are all important for the structure and function of the antibody, but they do not directly interact with the antigen.
