An approximately 8 kb region is deleted between PBac{WH}cmpyf02482 and PBac{WH}f01736. This region includes approximately 3 kb of upstream sequence, the translation initiation site and the majority of the coding sequence of cmpy. CG34260 is also partially deleted.
PCR to amplify from each side of the resulting hybrid PBac into genomic DNA verified the presence of PBac{WHr}.
