WebReproduction. Reproduction in prokaryotes is asexual and usually takes place by binary fission. Recall that the DNA of a prokaryote exists as a single, circular chromosome. Prokaryotes do not undergo mitosis. Rather the chromosome is replicated and the two resulting copies separate from one another, due to the growth of the cell. WebProkaryotes (bacteria and archaea) reproduce asexually through binary fission. Most prokaryotes reproduce rapidly. Due to their fast growth and simple genetics, E. coli bacteria are widely used in molecular biology. In the laboratory, a gene can be transferred into E. coli bacteria on a small, circular DNA molecule called a plasmid.
