The cell spends most of its life in Interphase which is composed of these 3 parts: -G1 (Gap 1, growth) -S phase (dna replication in preparation of cell division) -G2 (Gap 2, growth 2) Then if all the checkpoints are passed, the cell moves along to the Mitotic Phase which is composed of: -Mitosis -Cytokinesis In Mitosis: -Prophase (nuclear membrane is gone, dna is condensed) -Metaphase (chromatids are attached to spindle fibers and lined up in the center of the cell) -Anaphase (sister chromatids separate to opposite sides of the cell) -Telophase (the cell begins to split off to form two daughter cells, nuclear membrane is formed, cell is ready to separate) -----------END OF MITOSIS-------------- Next is Cytokinesis...the separation of cytoplasm and organelles. Now you have two new daughter cells and the cycle repeats. Hope that helps |
