Question

In antibody structure, which region is responsible for binding to specific antigens and differs between different antibodies?

Options

• Constant region

• Disulphide region

• Hinge region

• Variable region

Answer 1

The variable (V) region of each antibody chain serves as the antigen-binding site and differs between antibodies. This variation allows each antibody to recognize and bind to specific antigens, making each antibody unique in its targeting capability.
