Final answer:
When a successful joining of the light chain V and J segments occurs, it results in the formation of a unique variable region capable of binding a different antigen.
Step-by-step explanation:
When a successful joining of the light chain V and J segments occurs, it results in the formation of a unique variable region capable of binding a different antigen. When a successful joining of the light chain V and J segments occurs, it results in the formation of a unique variable region capable of binding a different antigen.
This joining happens through the process of genetic rearrangement of the V and J segments in the light chain gene. This rearrangement allows for over 10^6 possible VJ combinations, giving each differentiated B cell in the human body a unique variable chain.
