In this study , we tested this notion by using ligation - mediated PCR to assess the formation of recombination - activating gene ( RAG ) - dependent double - strand breaks ( DSBs ) at RSSs 3 ' of Ddelta3 and 5 ' of Jdelta1 .
 GENE: recombination - activating gene; GENE: RAG; GENE: Ddelta3; GENE: Jdelta1
