  7. Interphase Chromosomes in the nucleus are like a bunch of spaghetti noodles. For each chromosome there is an identical chromosome. This pair is called homologous chromosomes. Humans have 23 pairs of homologous chromosomes.

  8. Phase in Interphase • Scientists have established that interphase has three phases G1, S, and G2.

  9. Interphase - G1

  10. Interphase - S

  11. G2

  12. Mitosis • Mitosis is a continuous process. • PMAT • It is made up of 4 phases • Prophase • Metaphase • Anaphase • Telophase

  13. PMAT

  14. Prophase The first phase of mitosis is Prophase. 1) Chromosomes (DNA) twist (condense) into tight coils 2) Nucleus breaks apart

  15. Metaphase During Metaphase, all the chromosomes that are attached to the fibers move to the middle of the cell. The pairs line up end to end, across the center of the cell. “Meet in the middle”

  16. Anaphase During Anaphase, The chromosomes are pulled apart making 2 sister chromatids. The sister chromatids are pulled to opposite sides of the cell http://www.copernicusproject.ucr.edu/ssi/HSBiologyResources.htm

  17. Telophase During Telophase, a new nuclear membrane forms around the separated chromatids making 2 identical nuclei in 1 cell.
