Abstract
Chemostat-grown Escherichia coli showed recA(+)-dependent resistance to gamma radiation even though between 50 and 75% of the population possessed only a single unreplicated genome, suggesting that recombination between homologous chromosomes before replication is not necessary for manifestation of recA(+)-dependent resistance to gamma radiation.
摘要
恒化器培养的大肠杆菌对γ辐射表现出recA(+)依赖性抗性，尽管50%至75%的群体仅拥有单个未复制的基因组，这表明复制前同源染色体之间的重组对于recA(+)依赖性γ辐射抗性的表现并非必要。
