Question

The antigen-binding site of the antibody molecules is called ''paratope''. Epitope recognizing part of the antibody comprises of

• A. Variable part of heavy and light chains
• B. Constant paret of heavy chains
• C. Constant part of light and heavy & light chains
• D. N & C terminal of both heavy & light chains

Answer 1

The correct option is A Variable part of heavy and light chains

The part of an antibody that binds to the epitope is called a paratope. Although epitopes are usually non-self proteins, sequences derived from the host that can be recognized (as in the case of autoimmune diseases) are also epitopes.

So, the correct option is 'Variable part of heavy and light chains'.
