In 1946, Lederberg had discovered that E. coli bacteria could exchange genetic material between the cells by the process of conjugation (2341). The genetics of human nature. knowledge about the nature and behavior of living systems . 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.
