Abstract
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.
摘要
经紫外线照射的大肠杆菌K12 uvr+re在磷酸盐缓冲液中进行辐照后培养，其存活率有所提高。在该培养过程中，二聚体切除和DNA降解均受到抑制。这表明细菌以一种不涉及切除的方式应对剩余的二聚体。
