Document Summary

Three major processes are common to all forms of cell division/reproduction. They are dna replication, separation and segregation of the duplicated chromosome(s) into two separate nuclei, and division of the cytoplasm (cytokinesis). 2: there are three basic types of nuclear and cell division, binary fission (fig. 12): this is the simplest type of cell division mechanistically. It is characteristic of all prokaryotes and some single cell eukaryotes. It is a form of asexual reproduction: prokaryotes generally have just one circular chromosome, called a genophore, as dna replicates, each of the two resulting dna molecules attaches to the plasma membrane. As the bacterium grows, new plasma membrane is added between the attachment points, causing the dna molecules to move apart: cytokinesis, which is cell division, begins around 20 minutes after chromosome duplication is completed. In the middle of the cell a constricting ring forms in the plasma membrane.
