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
It was shown previously that a major class of UV-resistant derivatives of lexA- strains of E. coli K-12 is defective in cell division at 42.5 degrees. The thermosensitive mutations, judging by genetic mapping and complementation tests, are believed to be intragenic suppressor mutations that lower th
