Presentation Transcript

  1. Cell Cycle (Mitosis)

  2. California State StandardCell Biology (Mitosis) • 1. All living organisms are composed of cells. • e. cells divide to increase their numbers through a process of mitosis, which results in two daughter cells with identical sets of chromosomes.

  3. Cell Cycle 6 phases • Interphase • Prophase • Metaphase • Anaphase • Telophase • Cytokinesis Phases of Mitosis

  4. The Complete Cell Cycle

  5. Chromosome Structure Centromere

  6. Chromosome Structure So 1 chromatid + 1 chromatid = 1 Chromosome 1 chromatid 1 chromatid

  7. Interphase THE CELL: • grows to it’s mature size • makes a _____ of its DNA • prepares to _______ into two cells Copy Divide

  8. The DNA condenses

  9. Prophase Chromatin • the __________ condenses (gets thicker) to form chromosomes, which are two chromatids attached by a ____________. • _______ fibers stretch out to opposite ends of the cell • the nucleus breaks down Centromere Spindle

  10. Metaphase • the __________ line up in the middle of the cell • spindle fibers attach to the __________ of the chromosomes Chromosomes Centromere

  11. Anaphase Centromeres • ____________ split and the chromatids separate • chromatid to opposite ends of the cell being pulled by the ___________ • the cell begins to become stretched out Spindle Fibers

  12. Telophase Nucleus • the __________ reappears – two nuclei but one cell • chromosomes begins to loosen up (start to become string again)

  13. Cytokinesis • the cell divides and two new ___________ cells are formed • chromosomes loosen up and become chromatin again Daughter
