![]() ![]() The single, circular DNA chromosome of bacteria is not enclosed in a nucleus, but instead occupies a specific location, the nucleoid, within the cell. Because of the speed of bacterial cell division, populations of bacteria can grow very rapidly. The cell division process of prokaryotes, called binary fission, is a less complicated and much quicker process than cell division in eukaryotes. This type of cell division is called binary fission. Mitosis is unnecessary because there is no nucleus or multiple chromosomes. In bacterial cells, the genome consists of a single, circular DNA chromosome therefore, the process of cell division is simplified. ![]() The genomic DNA must be replicated and then allocated into the daughter cells the cytoplasmic contents must also be divided to give both new cells the machinery to sustain life. To achieve the outcome of identical daughter cells, some steps are essential. In unicellular organisms, daughter cells are individuals. In both prokaryotic and eukaryotic cells, the outcome of cell reproduction is a pair of daughter cells that are genetically identical to the parent cell. ![]() For unicellular organisms, cell division is the only method to produce new individuals. Prokaryotes such as bacteria propagate by binary fission. Explain how FtsZ and tubulin proteins are examples of homology.Describe the process of binary fission in prokaryotes.By the end of this section, you will be able to: ![]()
