5. CELL DIVISION MEISOIS MITOSIS Interphase Stages of mitosis: Prophase Metaphase Anaphase Telophase Interphase Stagesof meiosis: Prophase l Metaphase l Anaphase l Telophase l Prophase ll Metaphase ll Anaphase ll Telophase ll

6. Interphase G 1 PHASE: The cell grows by producing proteins and organelles. S PHASE: DNA synthesis G 2 PHASE: The cell makes final preparations for division.

7. Interphase

8. Chromosome Duplication

9. Prophase Nucleoli dissapear Chromatin fibers coil up to form chromosomes Spindle fibers are formed and attached to the centromeres of chromosomes Nuclear envelope breaks

10. Prophase

11. Metaphase Spindle fibers are fully formed Chromosomes are arranged in a line on an imaginary plane (metaphase plate= ekvator düzlemi)

12. Metaphase

13. Anaphase Centromeres of each chromosome come apart and sister chromatids are seperated Spindle fibers pull sister chromatids towards opposite poles of the cell

14. Anaphase

15. Telophase Nuclear envelopes form around identical sets of chromosomes at the two poles of the cell The chromosomes uncoil Nucleoli reappear Meanwhile cytokinesis begins

16. Telophase

17. Stages of Mitosis

19. Cytokinesis in animal cell (by cleavage furrow) Cytokinesis in plant cell (by cell plate)
