Cell Division (Chapter 18) 18.1 INCLUDE AN IMAGE THAT SHOWS THE CELL CYCLE 1. What are the three stages of interphase. Describe each phase. 2. How does interphase prepare a cell for cell division? 3. Define: mitosis, sister chromatids, centromere, cytokinesis, apoptosis 18.2 INCLUDE LABELED IMAGES OF THE PHASES OF MITOSIS 4. Following mitosis, how does the chromosome number of the daughter cell compare with the chromosome number of the parent cell? 5. What are the phases of mitosis and what happens during each phase? 6. How is the cytoplasm divided between the daughter cells following mitosis? 7. Define: parent cell, daughter cell, diploid, centrosome, mitotic spindle, centrioles. 8. What is the importance of mitosis and how is the process controlled?

Cancer is the number 2 cause of death in the united states over the last 50 years heart disease has increased a lot but cancer deaths have barely increased at all lung cancer is the most common cancer for both males and females for females the second most common cancer is breast for males the second most common cancer is prostate and colon men cancer deaths in 2007 was 289,550 Women cancer deaths in 2007 was 270,100 cancer levels are raising more and more and are just not starting to level out started putting warning levels on smoking in about 1975 stomach cancer has decreased asian/pacific islander seem to get the least amount of cancer

Introduction to Cancer Biology** one of the cells when an organ or tissue becomes damaged or altered in a way that causes it to break free from the normal controls that allows us to work together in harmony cells misbehave organs control eating, breathing, and moving tissue- muscle tissue, nervous tissue, epithelial tissue, connective tissue organ- made of a combination of tissues A normal cell divides when it receives a chemical signal these signals are interpreted in the nucleus and they reproduce this information--> mitosis cancer cells will divide even when they haven't received these chemical signals cells are also told when to stop dividing one of the main signals for a cell to stop dividing is when it comes in contact with another cell (contact inhibition) cancer cells don't do this and they just keep dividing and then you get a tumor that just continues to get bigger and bigger cancer cells continue to reproduce instead of stopping, so they just continue to divide and divide smaller structures of cells help perform their jobs nucleus is most important--brains of cell and contains chromosomes 46 chromosomes in each human nucleus genes are made of DNA changes to the DNA cause some genes to not do their job alteration in a gene caused by chemicals not supposed to be in the body, or radiation, or sometimes they just happen proto-oncogene- has the information to trigger cell division oncogene- mutation in a proto-oncogene cell divides with out signal to do so two copies of each gene so if one is damages the other can help the gene from acting abnormal like brakes tumors make the body provide them with nutrients spread of tumors to different locations around the body because blood vessels have reached the tumor 90 percent of the deaths due to cancer are because of tumors that have moved to other parts of the body prevention cells damaged first try to fix the problem and then the cell just commits suicide cancer cells can't do this, they don't kill themselves of try to fix themselves
