![]() ![]() The precise timing and formation of the mitotic spindle isĬritical to the success of eukaryotic cell division. When the new cell walls are in place, the daughter cells separate. A septum is formed between the nucleoidsįrom the periphery toward the center of the cell. After the chromosomes have cleared the midpoint of the elongated cell, cytoplasmic separation begins. As the cell elongates, the growing membrane aids in the Replication of the DNA is bidirectional-moving away from the origin on both strands of the DNA loop simultaneously.Īs the new double strands are formed, each origin point moves away from the cell-wall attachment toward opposite ends of the cell. The starting point of replication, the origin, is close to the binding site of the chromosome to the plasma membrane ( Figure 6.9). The packing proteins of bacteriaĪre, however, related to some of the proteins involved in the chromosome compaction of eukaryotes. As in eukaryotes, the DNA of the nucleoid is associated with proteins that aid in packaging the molecule into a compact size. The single, circular DNA chromosome of bacteria is not enclosed in a nucleus, but instead occupies a specific location, ![]() Because of the speed ofīacterial 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.
