Immunoglobulins are grouped into classes on the basis of similarities in which of the following?

Question

Quizplus · Accepted Answer

Immunoglobulins are grouped into classes based on the similarities in their heavy chains. The heavy chains contain constant regions that define the various classes of immunoglobulins (IgM, IgG, IgA, IgE, and IgD). The light chains contribute to the diversity of antigen binding sites, but they are not used to classify immunoglobulins into classes. Disulfide bonds are important for stabilizing the structure of immunoglobulins, but they are not used to classify the different classes.
