Hfr cell


An hfr cell is a bacterium with a conjugative plasmid integrated into its genomic DNA. Hfr is the abbreviation for high frequency recombination, which was first characterized by Luca Cavalli-Sforza. Unlike a normal F+ cell, hfr strains will, upon conjugation with a F− cell, attempt to transfer their entire DNA through the mating bridge, not to be confused...
