Document Summary
The process by which a single cell becomes 2 daughter cells: prokaryotic. Cells divide by mitosis and cytokinesis: binary fission. Each daughter cell receives one copy of the replicated parental dna: mitotic cell division. Dna in cytoplasm: eukaryotes: mitosis vs. meiosis, meiosis: leads to the production of gametes (eggs and sperm) Daughter cells have half the amount of genetic material as the parent cell: mitosis leads to the production of all other cell types, referred to as somatic cells. Genetic material is copied and then divided equally. Daughter cells are genetically identical to the parent cell: cell cycle, interphase: all phases of the cell cycle except for m, phases: G(cid:883) phase: (cid:498)gap(cid:499) phase, size and protein content increases. G(cid:884) phase: (cid:498)gap (cid:884)(cid:499), lag prior to mitosis and cytokinesis: m phases: mitosis and cytokinesis (not part of interphase) G0 phase: no active preparation for division- e. g. liver cells, nerve cells, lens of the eye.
