FIG. 6.

In vivo recombination between circular and linear DNAs bearing two different regions of luciferase homology. The experiments were identical to those shown in Fig. 5, except that linear DNA LucM20 or LucM333 was used instead of plasmid clones encoding these same DNAs (inset). The data are plotted on the same scale as that for Fig. 5 to facilitate direct comparison.
