  5. Stages of Interphase?
    (3)
    • G1
    • S
    • G2
  6. Interphase:
    Growth and development stage
    G1
  7. Interphase:
    "Synthesis" DNA is replicated
    S
  8. Interphase:
    Organelles are replicated
    G2
  9. Type of DNA found in Interphase?
    Chromatin
  10. What are the three forms of DNA?
    • Chromatin
    • Chromosomes
    • Chromatid
  11. DNA:
    Contain genetic material
    Thin barely visible strands of DNA
    1/2 of a chromosome
    • Chromosomes
    • Chromatin
    • Chromatid
  12. Process in which the nucleus divides to form two identical nuclei each with the same # of chromosomes
    Mitosis
  13. What is formed in Mitosis?
    2 Identical nuclei
  14. Steps of Mitosis?
    (4)
    • Prophase
    • Metaphase
    • Anaphase
    • Telophase
  15. Type of DNA in Prophase?
    Chromosomes
  16. What disappears in Prophase?
    • Nucleolus
    • Nuclear Membrane
  17. Prophase:
    What moves to the opposite ends of the cell?
    Centrioles
  18. Prophase:
    What begins to move across the cell?
    Spindle Fibers
  19. Shortest phase of Mitosis?
    Metaphase
  20. Metaphase:
    What happens?
    (2)
    Chromosomes line up in the middle of the cell and attach to spindle fibers
  21. What kind of DNA is in Metaphase?
    Chromosomes
  22. What kinds of DNA are in Anaphase?
    Chromatid
  23. What kind of DNA is found in Telophase?
    Chromatin
  24. What happens in Anaphase?
    (2)
    • Centromere divides
    • Chromatids move to opposite sides of the cell
  25. Telophase:
    What starts to disappear?
    Spindle Fibers
  26. Telophase:
    What uncoils into Chromatin?
    Chromatids
  27. Telophase:
    What begins to form?
    (2)
    • Nuclear Envelope
    • Necleolus
  28. Telophase:
    What is the difference between plant and animal cells are about to divide?
    • Animal Cells:
    • The cell membrane pinches together in the middle and breaks apart by a cleavage furrow

    • Plant Cell:
    • A Cell Plate is formed between 2 nuclei
  29. Cytoplasm Division
    Cytokinesis
  30. Cytokinesis:
    What is formed?
    Nucleus
  31. Cytokinesis:
    What are the results in Animal and Plant cells?
    They result in 2 identical cells with the same # of chromosomes
  32. In Cytokinesis what happens?
    The cell splits into 2 new cells, going back to Interphase
  33. In Plant Cells Mitosis takes....
    20 minutes
  34. In Animal Cells mitosis takes....
    80 Minutes
