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: -C) The structure involves the alignment of two heavy and light peptide chains linked with disulfide bridges in a Y-shaped structure forming arms and a stem. Thus, the statement is true.
Detailed explanation-3: -Antibodies are composed of four polypeptides: two identical heavy chains (large peptide units) that are partially bound to each other in a “Y” formation, which are flanked by two identical light chains (small peptide units).
