However bacteria do have mechanisms for bringing together DNA from different individuals. One of these mechanisms is bacterial conjugation a process that results in the direct transfer of genetic material from one bacterium to another. The figure shows two examples of bacterial conjugation. In these examples bacteria with a segment of DNA called an F factor are able to initiate conjugation. An F factor is a piece of DNA that contains about 25 genes. Most of the genes in the F factor are related to the production of a structure called a mating bridge. The mating bridge links two bacterial cells during conjugation allowing for DNA transfer. The F factor may be found on a separate piece of DNA called an F plasmid shown in part (a) of the figure. Or it may be found within the main bacterial chromosome shown in part (b) of the figure. Show less
