Pyrimidine dimer excision and DNA degradation during liquid holding recovery in ultraviolet-irradiated Escherichia coli K12 uvr+ rec.
The survival of ultraviolet-irradiated Escherichia coli K12 uvr+re was increased by post-irradiation incubation in phosphate buffer. During this incubation both dimer excision and DNA breakdown were inhibited. It is suggested that the bacteria coped with the remaining dimers in a manner which did not involve excision.
