A tenfold increase in the spontaneous reversion frequency of two of six lacZ frameshift mutations tested was observed in strains containing the following DNA polymerase I mutations--polA1, polA5, polA6, polAex1, res-3 and resA1. Reconstruction experiments indicated that this increase was not the res
