In addition , the results suggest that N region diversity at V ( D ) J junctions within rearranged immunoglobulin and T cell receptor gene loci can only be introduced after the generation of RAG - catalyzed DNA double - strand breaks , i . e . during the DNA end joining phase of the V ( D ) J recombination reaction .
