Popis: | Several strains of Escherichia coli K-12 harboring two F factors were isolated from Hfr x Hfr crosses. These strains were transiently capable of initiating chromosome transfer from two separate points of origin, and of transferring two different sex factors as integrated chromosomal markers. Each strain tested invariably reverted to a simple Hfr by loss of one of the inherited F factors. The F factor persisting in the revertant was, in nearly every case, that which had been inherited from the recipient Hfr parent. |
