Answer :
Antibodies consist of three polypeptide chains and assist in destroying particular antigens. They are shaped like the letter Y, not the letter B. Antibodies are not generalists in that any antibody can bind to any antigen; they are highly specific and can only bind to their target antigen.
Antibodies are proteins that are produced by the immune system to protect the body from foreign substances, called antigens. Antibodies are one of the body’s primary defense mechanisms against disease-causing microorganisms and other harmful substances. They are shaped like the letter Y and consist of three polypeptide chains: two identical heavy chains and two identical light chains.
The heavy and light chains of the antibody each have their own domains and binding sites. These domains and binding sites enable the antibody to recognize and bind to antigens. The antigen binding sites are located on the ends of the Y-shaped antibody and are composed of amino acid sequences known as complementarity determining regions (CDRs). These CDRs enable the antibody to recognize and bind to specific antigens.
