Question

The diagram shows an antibody molecule. Identify $A$ to $F$.

• A. $A$ - Antigen binding site; $B$ - Variable region (of $L$-Chain); $C$ - Constant region (of $L$-Chain); $D$- Light polypeptide chain ($L$-Chain); $E$- Heavy polypeptide chain ($H$-Chain); $F$ - Disulfide (bond)
• B. $A$ - Antigen binding site; $B$ - Constant region (of L-Chain); $C$ - Variable region (of L-Chain); $D$ - Light polypeptide chain (L-Chain); $E$ - Heavy polypeptide chain (H-Chain); $F$ - Disulfide (bond)
• C. $A$ - Antigen binding site; $B$ - Variable region (of L-Chain); $C$ - Constant region (of L-Chain); $D$ - Heavy polypeptide chain (L-Chain); $E$ - Light polypeptide chain (H-Chain); $F$ - Hydrogen (bond)
• D. $A$ - Antigen binding site; $B$ - Variable region (of L-Chain); $C$ - Constant region (of L-Chain); $D$ - Light polypeptide chain (L-Chain); $E$ - Heavy polypeptide chain (H-Chain); $F$ - Hydrogen (bond

Answer 1

Answer: (A)

Correct answer is (a) $A$ - Antigen binding site; $B$ - Variable region (of $L$-Chain); $C$ - Constant region (of $L$-Chain); $D$- Light polypeptide chain ($L$-Chain); $E$- Heavy polypeptide chain ($H$-Chain); $F$ - Disulfide (bond)
