  1. Review of Cell Cycle I play music at the club

  2. Name the 3 Parts of the Cell cycle 1) Interphase: • Gap1: growing, carying out normal cell function. • Synthesis: copies its DNA in preparation for cell division • Gap2: Cell prepares for division of the nucleus 2) Nuclear division: Mitosis 3) Cytokinesis

  3. Name and describe the 4 phases of mitosis ( in order) Prophase: • Nuclear membrane breaks down • Nucleolus disappears • Chromosomes coil and thicken • Spindle begins to form between the centrioles

  4. Metaphase: • Chromosomes attach to the spindle and align along the equator of the cell. Anaphase • Microtubules shorten, moving chromosomes to opposite poles.

  5. Telophase: • Chromosomes reach poles of cell • Nuclear envelope re-forms • Nucleolus reappears • Chromosomes decondense

  6. What is a sister chromatid? • Sister chromatids are structures that contain identical copies of DNA and are attached together with a centromere

  7. What is cytokinesis? Cytokinesis: a process that divides the cytoplasm which results in two cells, each with identical nuclei.

  8. Centromere: joins the two sister chromatid • Spindle: The apparatus that moves and organizes the chromosomes before cell division. • Chromosome: A single copy of DNA • Chromatin: All the chromosomes in a relaxed state (during interphase) • Sister chromatids: two copies of DNA

  9. Cancer • Cancer is uncontrolled cell division
