Replication-loop dynamics depend on primase activity. Loop growth and lag times are compared for different concentrations of ribonucleotides. Replication-loop lengths and lag times were determined as described in Figure 1. For loop lengths, sample size n=288 at 300 µM ATP, 300 µM CTP; n=61 at 30 µM ATP, 10 µM CTP; and n=72 at 30 µM ATP, 10 µM CTP, 300 µM pAC. For lag times, n=135 at 300 µM ATP, 300 µM CTP; n=25 at 30 µM ATP, 10 µM CTP; and n=30 at 30 µM ATP, 10 µM CTP, 300 µM pAC.
