Deletions of the uvrB gene were not obtained in polA1 strains of Escherichia coli either by selecting for spontaneous deletions or by transduction from strains carrying such deletions. A strain forming a temperature-sensitive deoxyribonucleic acid polymerase I and carrying a deletion of the uvrB gene is inviable at the nonpermissive temperature.
在大肠杆菌的polA1菌株中,无论是通过选择自发缺失还是从携带此类缺失的菌株进行转导,都无法获得uvrB基因的缺失。一个形成温度敏感型脱氧核糖核酸聚合酶I并携带uvrB基因缺失的菌株在非允许温度下无法存活。
