WebBacteria divide very rapidly. The doubling time is also called generation time and it may be as low as 20 minutes. Bacteria mainly reproduce by asexual reproduction but do not exhibit true sexual reproduction as they do not produce diploid phase. Thus, meiosis is lacking. However, bacteria exchange genetic material between two cells. WebGenetic Exchange Between Bacteria. Part of the genetic material of a donor cell can be transferred to a recipient cell. After the transfer, recombination between the donor and recipient DNA may occur followed by succeeding nuclear and cell division. The model for recombination is as follows: Homologous DNA strands pair.
