Question

Quizplus · Accepted Answer

The region of immunoglobulins that form the structural site complementary to some part of an antigen's structure are the hypervariable regions. These regions are also known as complementarity-determining regions (CDRs) and are located within the variable domain of the heavy and light chains. The hypervariable regions are responsible for the incredible specificity of antibodies and allow them to recognize a vast array of antigens. The other choices are incorrect. The immunoglobulin fold region refers to the conserved structure of the antibody molecule. The hinge region is a flexible region that connects the heavy and light chains. The constant heavy region refers to the conserved region of the heavy chain, and it doesn't play a role in antigen specificity.
