Mechanisms of Microbial Genetics. Typically the process requires a donor cell that at some point lysed and released naked DNA to the environment. 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. Microbial Genetics. Griffith experiment was a stepping stone for the discovery of genetic material. Some fungi and protozoa are also subjects used to study in this field.

Cohan suggests this exchange happens at a low frequency (10-8 to 10-7 exchanges per gene segment per genome per generation). This involves both discovering the regulatory genes and sites that control individual gene expression and determining which genes are coregulated and, thus, likely to participate in the same process.
