Each antibody has \(\underline{A}\) polypeptide chains, \(\underline{B}\) small chains called \(\underline{C}\) chains and \(\underline{D}\) longer chains called \(\underline{E}\) chains. The antibody, therefore, is represented as \(\underline{F}\).
Here A to F refers to:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) -A–four, B–two, C–light, D–two, E–heavy, F–H 2L2
Antibodies, also known as immunoglobulins, are protein molecules produced by B-cells as part of the immune response. Each antibody consists of several polypeptide chains. The structure of an antibody includes two types of chains: light chains and heavy chains.
In the given options, the correct representation of the antibody structure is as follows:
A – Antibodies have four polypeptide chains in total.
B – There are two small chains called light chains.
C – The small chains are referred to as light chains.
D – Antibodies have two longer chains called heavy chains.
E – The longer chains are referred to as heavy chains.
F – The antibody structure is represented as H2L2, indicating two heavy chains and two light chains.
Therefore, the correct option is (a) A–four, B–two, C–light, D–two, E–heavy, F–H2L2.
