During the course of analyzing circular DNA in mouse thymocytes, novel recombinants were identified with immunoglobulin heavy chain joining gene and switch region probes. These circles represent excision products of recombination between the heptamer-nonamer motif for V-(D)- J joining and a repetitive sequence for class switching. The molecular mechanisms that generate "hybrid circles" are discussed.
