An antibody is specific to an antigen because its polypeptide subunits have specific tertiary structures forming a binding site complementary to a specific antigen, allowing antibody-antigen complex formation.
Un anticuerpo es específico para un antígeno porque sus subunidades polipeptídicas tienen estructuras terciarias específicas que forman un sitio de unión complementario a un antígeno específico, permitiendo la formación de un complejo anticuerpo-antígeno.
| Front | Why is an antibody specific to an antigen? |
|---|---|
| Back | - polypeptide subunits have specific tertiary structures - giving the binding site a specific shape - which is only complementary - to the specific tertiary strucure and shape - of the antigen - causing an antibody-antigen complex to form |
