- MITOSIS
- 4) TELOPHASE
- the chromosomesare cordened off into distinct new nuclei in the emerging daughter cells
- nuclei form at different poles; nuclei envelopes formed; nucleoli reappear; chromatin fibers uncoil; cell divided equally into two
- 3) ANAPHASE
- sister chromatids separate and begin to move to opposite ends of cell; at the end of anaphase, each pole contains a complete compilation of chromosomes
- the paired centromeres in each distinct chromosome begin to move apart; these are now daughter chromosomes; daughter chromosomes move to opposite poles; the two poles move farther apart; each pole now contains a compilation of chromosomes
- 1) PROPHASE
- chromatin condenses; nuclear envelope breaks; spindles form at opposite poles of the cell
- chromatin fibers coil into chromosomes; each chromosome has 2 chromatids joined at a centromere; the mitotic spindle forms in the cytoplasm; two centrioles move away from one another due to lengthening of microtubules
- CYTOKINESIS
- division of the cell's cytoplasm to form two distinct daughter cells
- 2) METAPHASE
- sprindle fully develops; chromosomes align at the equator
- nuclear membrane disappears completely; two centrioles align at each pole
- 4) TELOPHASE
