Verified
Which portion of the antibody binds to the antigen?
A) variable region
B) constant region
C) heavy chain
D) light chain
Antibody
Protein produced in response to the presence of an antigen; each antibody combines with a specific antigen.
Antigen
A substance that stimulates an immune response, especially the production of antibodies, because it is recognized by the body as foreign.
Variable Region
A region in an antibody's structure that varies among different antibodies, allowing them to bind to a vast array of antigens.
- Absorb the core principles of clonal selection theory and its pivotal importance in the mechanism of adaptive immunity.

Final Answer :
A
Explanation :
The variable region of the antibody binds to the antigen. This region is responsible for the specificity of the antibody as it contains unique amino acid sequences that allow it to recognize and bind to a specific antigen. The constant region, heavy chain, and light chain are all important for the structure and function of the antibody, but they do not directly interact with the antigen.
