Multiple integration sites for the lactose transposon Tn951 on plasmid RP1 and establishment of a coordinate system for Tn951

Abstract
Various molecules generated by transposition of the lactose transposon Tn951 from plasmid pGC1 to plasmid RP1 were examined by DNA heteroduplex and restriction endonuclease analysis. Tn951 was found to transpose to at least eight different sites on RP1 in both possible orientations. A coordinate system for the lactose transposon Tn951 is constructed.
