  1. The process by which a cell divides into two new daughter cells.
    Cell Division
  2. In what two stages do eukaryote cells are during cell division?
    • Mitosis (Division of the cell nucleus)
    • Cytokinesis (Division of the cell cytoplasm)
  3. Genetic info that is passed from one generation to the next.
    Chromosomes
  4. Before cell division, each chromosome is _____. Each chromosome consists of ___ identical "sister" chomatids.
    • Copied; duplicated
    • 2
  5. Each pair of chromatids is attached at what area?
    Centromere
  6. The series of events that cells go through as they grow and divide.
    Cell Cycle
  7. The period/ phase of growth that occurs between cell division.
    Interphase
  8. G1, S Phase, 52, and M Phase are the four phases of what?
    The Cell Cycle
  9. What cell cycle phase increases in size and synthesizes new proteins and organelles?
    G1
  10. What cell cycle phase makes chromosomes replicated and DNA synthesis takes place; usually completes the rest of the cycle.
    S Phase
  11. What cell cycle phase is organelles and molecules required for cell division are produced; once complete, starts M Phase.
    G2
  12. What are the four phases of Mitosis (first - last)?
    Prophase, Metaphase, Anaphase, and Telophase.
  13. Region of where centrioles lie; helps organize spindle.
    Centrosome
  14. What phase of mitosis is the longest, in which the centrioles separate and take up positions on opposite sides of the nucleus. Chromatin condenses into chromosomes and the centrioles separate and a spindle begins to form and the nuclear envelope breaks down.
    PROphase
  15. A fanlike microtubule structure that helps separate chromosomes.
    Spindle
  16. What mitosis phase makes the chromosomes line up across of the cell; microtubles begin to connect the centromere of each chromosome to the poles of the spindle.
    METAphase
  17. What mitosis phase is the sister chromatids sparate into individual chromosomes, The chromosomes continue to move until they have separated into two groups.
    ANAphase
  18. What mitosis phase gathers chromosomes at opposite ends of the cell and lose their shape; a new nuclear envelope forms around each cluster of chromosomes.
    TELOphase
  19. What is only found in plant cells; a structure that forms between the divided nuclei?
    Cell Plate
  20. Not to grow; caused by cells come in contact with other cells; demonstrates that controls on cell growth and division can be turned on or off.
    Contact Inhibition
  21. A protein in which is regulated by the cell cycle; regulate the timing in eukaryotic cells.
    Cyclins
  22. What are the worst and harmless types of cancer?
    • Malignant (Worst)
    • Benign (Harmless)
  23. A disorder in which some of the body's own cells lose the ability to control growth; do not respond to the signals that regulate the growth.
    Cancer
  24. Cancer cells that divide uncontrollably and forms masses of cells; damages the surrounding tissues.
    Tumors
  25. What can break loose from tumors and spread throughout the body, disrupting normal activities and causing serious medical problems or even death?
    Cancer cells
