FtsZ proteins can produce filaments, rings, and other three-dimensional characters approximating how tubulin shapes microtubules, centrioles, and various cytoskeleton components. Although, prokaryotes have an FtsZ (filamenting temperature sensitive mutant Z) protein that directs the partition between the nucleoids and possesses a cytokinesis that has architectural similitude with tubulin, which are the constituents making up the mitotic spindle of eukaryotic cells. Since mitosis is crucial to eukaryotic cells, and they therefore have a mitotic spindle, prokaryotic cells do not have this. Mitosis and meiosis take place in eukaryotic cells and are more advanced. Replication of the DNA is bidirectional-shifting away from the origin on both strands of the DNA disc simultaneously. Whereas binary fission takes place in prokaryotic cells of simple single-celled organisms such as bacteria. They are powered by ATP Mitotic spindle How. The starting point of replication, the origin, is near the binding site of the chromosome to the plasma membrane. These are tubes of protein which use to pull chromosomes apart and to opposite ends of a cell during mitosis. Instead, prokaryotes contain a membrane-less, irregularly shaped region called the nucleoid for housing their genetical material and a chromosome that is very large compared to the proportions of the cell to therefore be firmly packed and pressed together to fit in the cell. Compared to the cell structure of eukaryotic organisms, the cell structure of prokaryotes (e.g. Mitosis cannot be done for them because they do not possess nuclei nor multiple chromosomes. Mitosis Binary Fission For simple organisms like bacteria, cell division (for propagation) is dependent on a form of asexual reproduction known as binary fission. However, prokaryotes such as bacteria pullulate by binary fission which is more efficient than the mitosis for eukaryotes. Our cells and tissues grow and multiply by mitosis.
