Abstract
According to mutation mapping after nitrosoguanidine treatment of successive samples obtained from a synchronized culture of Escherichia coli K12 carrying an R factor, it was found that the majority of mutations of the R factor were produced after a maximum peak of galactose mutant production. According to the order of the chromosome replication and the initiation point of the replication, these facts suggest that the replication of the R factor occurs after the replication of the galactose gene. The transfer frequency of the R factor from a synchronized donor culture to the nonsynchronized recipient was the highest after the replication of the chlotamphenicol gene on the R factor, probably after the replication of the R factor genome. The recipient ability of the R factor in a synchronized recipient culture from a nonsynchronized donor was the highest after a maximum peak of the galactose mutation, and probably after the cell division in the recipient.
