Explanation:
Detailed explanation-1: -Antigen binding site, also known as paratope is a part of an antibody which recognizes and binds to an antigen. It is a small region of 5 to 10 amino acids of the antibody’s Fv region, part of the fragment antigen-binding (Fab region), and contains parts of the antibody’s heavy and light chains.
Detailed explanation-2: -When the VH and VL domains are paired in the antibody molecule, the hypervariable loops from each domain are brought together, creating a single hypervariable site at the tip of each arm of the molecule. This is the binding site for antigen, the antigen-binding site or antibody combining site.
