Transduction is the process by which bacterial DNA is moved from one bacterium to another by a virus. Transduction, a process of genetic recombination in bacteria in which genes from a host cell (a bacterium) are incorporated into the genome of a bacterial virus (bacteriophage) and then carried to another host cell when the bacteriophage initiates another cycle of infection. E. coli phage lambda is a classic example of a specialized transducing phage that integrates its DNA precisely between operons encoding enzymes responsible for galactose (gal) and biotin (bio) utilization in the E. coli chromosome.
