The increased sensitivity of Escherichia coli to killing by ultraviolet irradiation when frozen and the variation in this sensitivity as a function of the temperature during irradiation have been correlated with changes in the amount of DNA that was cross-linked to protein by ultraviolet light. These variations in sensitivity to killing do not correlate with the production of thymine dimers.
冷冻时大肠杆菌对紫外线照射杀伤的敏感性增加,以及这种敏感性随照射期间温度的变化,已与紫外线使DNA与蛋白质交联的量的变化相关联。这些杀伤敏感性的变化与胸腺嘧啶二聚体的产生无关。
