Read the following Assertion and Reason and choose the correct option. Assertion: Antibodies are made up of two light chains and two heavy chains. Reason: An antibody is represented as H2L2, where H stands for heavy chains and L stands for light chains.

Step-by-step solution

The B-lymphocytes produce an army of proteins in response to pathogens into our blood to fight with them. These proteins are called antibodies. The T-cells themselves do not secrete antibodies but help B cells to produce them. Each antibody molecule has four peptide chains, two small called light chains and two longer called heavy chains. Hence, an antibody is represented as H2 L2 . Different types of antibodies are produced in our body. IgA, IgM, IgE, IgG are some of them. A cartoon of an antibody is given in Figu
