Which of the following is not correct regarding the structure of an antibody? a. The ends of the variable regions of the polypeptides in an antibody form antigen-binding sites. b. The polypeptides making up an antibody are connected by covalent bonds c. Larger polypeptides making up an antibody are called heavy chains d. Each polypeptide in an antibody has a constant region and a variable region e. An antibody is made up of two polypeptide chains linked by hydrogen bonds

Solution

Thanks for posting question. Option e is incorrect. Immunoglobulin(antibody) molecules are composed of two types of protein chains: heavy chains and light chains. Each immunoglobulin molecule is made up of two heavy chains and two light chains joined by disulde bonds so that each heavy chain is linked to a light chain and the two heavy chains are linked together.
