Determination of the rate constants for the exonucleolysis of primer-templates. Data, obtained from gels similar to those shown in Figures 2 and 3, were fitted to a first order decay to show the disappearance of substrate. Only the data obtained with the AA/TT series is shown (similar quality fits were obtained with the GC/CG set). For U+2, a rapid quench apparatus was used; for the other three primer-templates, manual stopping of the reactions was sufficient. The rate constants found are given in Table 2.
