abstract：:The products of the RAG-1 and RAG-2 genes are essential for the recombination of the DNA encoding the antigen receptors of the developing immune system. Little is known of the specific role these genes play. We have explored the sequences encoding mouse RAG-1 by deleting large parts of the gene and by introducing loca...
