title: Transposition of the lac region to the gal region of the Escherichia coli chromosome: isolation of lambda-lac transducing bacteriophages.
abstract: Defective and plaque-forming lambdalac transducing phages have been isolated from bacterial strains in which the lactose operon has been genetically transposed to the galactose locus.
