Abstract
The number of pyrimidine dimers (sites sensitive to UV-endonuclease from M. luteus) transferred at 43 degrees to daughter DNA strands during postreplication repair in UV-irradiated E. coli uvr A polCts was found to be decreased as compared to that after repair at 32 degrees. This indicates the involvement of DNA polymerase III in the sister DNA recombination in UV-irradiated E. coli.
摘要
在紫外线照射的大肠杆菌uvr A polCts中，复制后修复期间在43摄氏度转移至子代DNA链上的嘧啶二聚体（对藤黄微球菌紫外线内切酶敏感的位点）数量，与在32摄氏度修复后的数量相比有所减少。这表明DNA聚合酶III参与了紫外线照射的大肠杆菌中姐妹DNA的重组。
