Document Summary
Binary fission: copy dna and split into tow identical cells. 1 bacteria = 10 bil bacteria in 10 hours. Binary fission allows prokaryotes to quickly and efficiently grow their population without the expense of too much energy. Homologous chromosome: identical chromosomes in genetic loci and centromere placement. Homologous pair with same genetic info for same character. Where spindle fibers attach to chromosome during cell division. Without the centromere spindle fibers are not able to attach to the chromosome and pull it apart during mitosis. End result of cell cycle is two daughter cells with the same genetic makeup as the parent cell. Divides cytoplasm and its contents into two new cells. G1 (growth one): in this stage the cell goes through growth. G0: if the cell is not big enough or is not ready to divide it stays in this phase until it is. S checkpoint: this is the final check before cell division occurs.
