Question

Each individual antigenic determinant of the variable region of the antibody is referred to as:

• A. paratope
• B. epitope
• C. agretope
• D. idiotope

Hint:

Epitope = antigen’s determinant, Paratope = antibody’s binding site, Idiotope = antibody’s unique variable determinant.

Answer 1

The Correct Option is D

Step 1: Understanding terms.
- Paratope: Antigen-binding site of the antibody.
- Epitope: Antigenic determinant present on the antigen.
- Agretope: Part of antigen that binds to MHC molecules.
- Idiotope: Each unique antigenic determinant in the variable region of the antibody itself. Step 2: Conclusion.
Thus, the correct term for antigenic determinants of the antibody variable region is idiotope.
Final Answer: \[ \boxed{\text{idiotope}} \]
