Answer
Identify the Statement that is NOT Correct
- (1) Each antibody has two light and two heavy chains. ✔ Correct
- (2) The heavy and light chains are held together by disulfide bonds. ✔ Correct
- (3) Antigen binding site is located at C-terminal region of antibody molecules. ✖ Incorrect
👉 The antigen-binding site is at the N-terminal region of the variable domains. - (4) Constant region of heavy and light chains are located at C-terminus of antibody molecules. ✔ Correct
Final Answer: Statement (3) is NOT correct.
Summary Table
| Chain Type | Terminal Region | Function |
|---|---|---|
| Light & Heavy | N-terminal | Variable region – Antigen binding |
| Light & Heavy | C-terminal | Constant region – Effector function |
