Document Summary
Chapter 9 part 2 of 3 (begin material for exam 3) During interphase a cell _grows_, _replicates its dna_, and often _differentiates_ Most eukaryotic cells spend the majority of their time in ______interphase___________ Ex: human skin cells replicate about once a day, spend about 22 h in interphase. Interphase contains three phases - g1, s, g2. During _g1_the cell: almost always grows in size, often _differentiates_ Decides whether or not to divide based on signals. If signals cause the cell to divide then the cell enters _s phase_ Once the cell enters s phase it is _committed to dividing_, there is no turning back! After s phase the cell enters ________g2 phase________: more growth. Gives each daughter nucleus one copy of the parent cells replicated chromosomes: ________cytokinesis_________ cytoplasmic division. Places each of the nuclei into each daughter cell. Mitotic cell division typically gives rise to two daughter cells that are genetically identical to each other and to parent cell.
