Question

The variable regions of the heavy and light chains form the ________ sites of an antibody.

Answer 1

Fab or fragment antigen binding

Step-by-step explanation:

Treating the antibody with a protease can cleave this region, producing Fab. that include the variable ends of an antibody. Material used for the studies .The constant region determines the mechanism used to destroy antigen. Antibodies are divided into five major classes, IgM, IgG, Iga, IgD, and IgE, based on their constant region structure and immune function.

Answer 2

Antigen binding fragments

Step-by-step explanation:

Antigen binding fragments are site locations that promote antigen-antibody binding, promoting complete protection of the organism. These fragments have specific molecules between antibody and antigen, so we can say that through the antigen binding fragments each antibody is antigen specific. In summary, we can state that the variable regions of the heavy and light chains form the antigen binding fragments sites of an antibody.
