Antibodies are composed of two types of peptides, heavy chains and light chains. One of the major classes of antibody molecules is immunoglobulin $\mathrm{G}(\mathrm{IgG})$. Two heavy chains and two light chains form one IgG molecule. Classify each statement as describing the heavy chains, light chains, or both chains of IgG. Answer Bank contain only one variable domain are found in the Fab fragment form the antigen-binding site are found in the Fc fragment contain only one constant domain contain multiple constant domains contain multiple variable domains
