Which of the following is/are true about antibody structure?
A
They are made of four polypeptides
B
The variable region is recognised by phagocytes
C
The constant region is where the antigen binds
D
The heavy chains only contain constant regions
Explanation: 

Detailed explanation-1: -Which one of the following is correct regarding the structure of an antibody? The four polypeptide chains that make up an antibody molecule are linked by disulfide bonds.

Detailed explanation-2: -Answer and Explanation: A) The terminal parts consist of structures that bind or attach specifically to the foreign molecules (i.e., antigens). Thus, the statement is true.

Detailed explanation-3: -Antibodies are proteins with around 150 kDa molecular weight. They have a similar basic structure comprising of four polypeptide chains held together by disulfide bonds. These four polypeptide chains form a symmetrical molecular structure.
