The complementarity-determining regions of an immunoglobulin G molecule The complementarity-determining regions of an immunoglobulin G molecule
A) are a feature of all immunoglobulin domains.
B) are located in the light but not the heavy chains.
C) participate in the covalent attachment of oligosaccharide groups.
D) specify interactions with antigens or epitopes.
E) stabilize overall protein structure.

Question

Quizplus · Accepted Answer

The complementarity-determining regions (CDRs) of an immunoglobulin G (IgG) molecule are responsible for specifying interactions with antigens or epitopes. These regions are located in the variable domains of both the heavy and light chains of an IgG molecule.

Therefore, option D is the correct answer. Options A, B, C, and E are incorrect as they do not accurately describe the function or location of CDRs in IgG molecules.
