FIG. 3.

Exonuclease I and the RecF pathway gene products contribute to the nascent DNA degradation at replication forks disrupted following DnaB(Ts) inactivation. Degradation was measured as described in the legend to Fig. 2B. (A) Relative amounts of degradation in the nascent DNA (filled symbols) and total genomic DNA (open symbols) plotted over time for dnaB(Ts) strain CRT266, dnaB(Ts) recD strain CL743, dnaB(Ts) xonA strain CL774, dnaB(Ts) recJ strain CL742, and dnaB(Ts) xonA recJ strain CL785 following a temperature shift to 42°C. (B) Relative amounts of degradation in the nascent DNA (filled symbols) and total genomic DNA (open symbols) plotted over time for dnaB(Ts) recG strain CL1024, dnaB(Ts) ruvAB strain CL1026, and dnaB(Ts) recA strain CL1028 following a temperature shift to 42°C. The symbols indicate the averages of three independent experiments. The error bars indicate one standard deviation. The dnaB(Ts) strain CRT266 plots in panels A and B were generated by separate investigators.
