Abstract
A new conditional thermosensitive Hfr mutant of Escherichia coli K-12 was isolated. The ts mutation is cotransducible with purE and tsx loci on the E. coli chromosome. Upon temperature shift to 42 degrees C the DNA synthesis and transfer of chromosome is stopped immediately and RNA, protein synthesis in about ten minutes.
摘要
分离出了一种新型的大肠杆菌K-12条件性热敏Hfr突变体。该温度敏感（ts）突变与大肠杆菌染色体上的purE和tsx位点共转导。当温度升至42摄氏度时，DNA合成和染色体转移立即停止，RNA和蛋白质合成在大约十分钟后停止。
