3. Cell Cycle

5. Mitosis in conjoined twins

8. Mitosis: Cell Division b A process that results in the creation of identical cells containing the same number of chromosomes as the parent cell. b Stages of Mitosis (PMAT) ProphaseProphase MetaphaseMetaphase AnaphaseAnaphase TelophaseTelophase

9. Prophase b Chromosomes get short & thick rods. b Nuclear Envelope dissapears. b Protein cables called spindle fibers form across the cell

10. Metaphase b Chromosomes line up across the middle of the cell. b Spindle fibers connect the centromere of each chromosome.

11. Anaphase b Each chromosome separates from its sister chromatids. b Chromosomes are reeled to opposite sides of the cell. b Spindle Fibers begin to break down.

12. Telophase b Final Phase b Chromosomes begin to uncoil and spindle fibers disappear. b Each side has a complete set of chromosomes. b The nuclear envelope reforms around each set of chromosomes.

13. Cytokinesis b Division of the cytoplasm into two individual cells. b Each new cell contains identical DNA. (chromosomes) b Animal cells= cell furrow b Plant cells= cell plate b After growth and replication, the cells may divide again.

14. Sequence correctly

15. Sequence correctly 5-3-1-4-2

16. Answer these questions. How would the chromosomes look during: Interphase Prophase In daughter cells How many chromatids are there in metaphase of mitosis of a human leg cell

28. Cancer Notes Cancer Notes b Cancer cells--Cells of your body that eat and divide out of control without performing the necessary function for your body b Cancer Death--Cancer cells take over an organ and cause it to dysfunction and you die.

29. Tumor types: b Malignant – spread to other places in your body. Grow into other organs and spread. b b Benign- The ceils of the tumor do not spread of invade other tissues.

30. Types of cancers. b Carcinomas – Most common type of cancer. They arise from cells that cover external and internal body surfaces. EX. Lung / Breast/ Colon/ Skin b b Sarcomas –Cells that arise from the supporting tissues. Bone/ Cartilage/ fat/ Connective/ Muscle b b Lymphomas - Cells that arise from the lymph nodes and tissues of the immune system. b b Leukemia’s – Cancers of the bone marrow and blood tissues.

31. Cancer Notes Cancer Notes b Metastasis – Penetrates lymphatic and blood systems and travels through the body. b Invasion – migrates and penetrates into neighboring tissues.

32. Cancer growth and spreading

33. Cancer recruits blood vessels
