BI110 Chapter Notes - Chapter 32: Walther Flemming, Cell Division, G1 Phase
Document Summary
Cell division one cell divides into two. When a parent cell divides, two daughter cells are genetically identical to parent cell. Cell division enables growth and the replacement of worn-out of damaged cells. Prokaryotes reproduce through binary fission, eukaryotic cells divide through either mitosis or meiosis. Mitosis is the process in eukaryotes of producing exact copies of the parent cell"s chromosomes and segregating them into separate nuclei, followed by cytokinesis to produce two daughter cells. Meiosis produces daughter cells that contain half the number of chromosomes of the parent cell; thus, the daughter cells are not exact copies (leads to formation of gametes, fuse with another gamete during sexual reproduction) The prokaryotic cell copies its genome, increases in size, and then splits into two daughter cells. With mitosis, each daughter cell contains the same number of chromosomes as the parent cell.
