title: Thymineless death in polA+ and polA- strains of Escherichia coli.
abstract: The extreme sensitivity of polA(-) cells to thymineless death is due, primarily, to the absence of an extended lag prior to the commencement of death. Once thymineless death has commenced, the rate in polA(-) cells is only slightly faster than in polA(+) cells.
