FIG. 3.

Effect of xonA, recJ, ΔruvAC, and ΔrecG mutations on the ratio of 5′ to 3′ heteroduplexes in intramolecular recombination products. The ratios of 5′ to 3′ heteroduplexes in DNA preparations of samples taken at the indicated times after infection are presented. Radioactivity was determined by phosphorimaging analysis of Southern hybridization patterns like the ones presented in Fig. 2. Relevant genotypes are indicated. Each value is a median of at least three independent experiments. The error bars represent the range.
