Figure 8.

Insertions of Tn10dTc at points far from lac on the F′ plasmid allowed AnTc to inhibit revertant yield. A series of tester strains with Tn10dTc inserted at various points in the F′lac plasmid were compared for their yield of Lac⁺ revertants following pregrowth with and without AnTc. These strains are described in Table 1. Revertant yields following pregrowth without and with AnTc are described in the top left and top right, respectively. The map positions of the Tn10dTc insertions are described in the bottom left.
