The Cell Cycle The Cell Cycle • Interphase Cell Growth and Preparation for Division • Mitosis Division of the Nucleus and its DNA • Cytokinesis Division of the Cytoplasm Interphase • Gap 1 Cell Growth • Synthesis DNA Replication • Gap 2 Organelle Replication Mitosis • • • • Prophase Metaphase Anaphase Telophase Prophase • During this phase, DNA in the form of Chromatin condenses into Chromosomes • The Nuclear Membrane disappears Metaphase • During this phase, Chromosomes line up at the Equator of the Cell • Centrioles migrate to the poles as Spindle Fibers attach to the Centromeres of the Chromosomes Anaphase • During this phase, the Chromosomes separate, with the aid of the Spindle Fibers, and move toward the poles of the Cell Telophase • During this phase, the Chromosomes reach the poles of the Cell • There they begin to uncoil into Chromatin, and the Nuclear Membrane reforms Mitosis Movies • • • • Movie 1 Movie 2 Movie 3 Movie 4 Cytokinesis • During this phase, the Cell Membrane constricts dividing the Cell into two fairly identical Cells
