Final answer:
The constant region genes encoding the light chain do not bear antigen binding CDRs. The statement is true
Step-by-step explanation:
The statement is true. The constant region genes that encode the constant region of the light chain do not bear antigen binding CDRs (Complementarity Determining Regions). The CDRs are located in the variable region of the light chain, specifically in the hypervariable regions, which are responsible for forming the antigen-binding surface of the immunoglobulin molecule.
