Reproduction The principal mode of reproduction is an asexual separation of one bacterium into two. There are, in  addition, several mechanisms that make possible the exchange of genetic material, the DNA, among  and between bacterial cells. None, however, are as elaborate as the mitosis—meiosis choreography  of gene exchange in the eukaryotes. Asexual Three common types of asexual reproduction are present: Binary fission  (the most common): The “chromosome” replicates and the two  genomes move to opposite ends of the cell. The old cell walls then grow inward between  the two, pinching the cell apart—no mitosis, no microtubules. The whole process is over  within 30 minutes to three hours.  Fragmentation : This occurs when filaments of cells break into separate pieces or  fragments Budding : An outgrowth (  bud ) pushes out from the cell, pinches off, and then
