5. 5 M (mitosis) G1 (Gap 1) G2 (Gap 2) S (DNA Synthesis) Cells that cease division

6.  a protective section of DNA at the end of each chromosome.  get shorter every time the cell divides.  Cyclin 6

7. 7 Cdk MPF P53 P27

8.  When the telomere becomes too short, the cell dies.  Cells that rebuild the telomere with each division can become cancerous 8

11.  genetic information is carried in a single, circular chromosome.  DNA is attached at one site to the cell membrane. 11

12.  much more DNA than Prokaryotes.  genetic information is organized into linear chromosomes.  float freely in the nucleus. 12

13. 13

14.  One parent  Same genetic blueprint as the parent (clone) 14

15.  Binary Fission  Budding  Parthenogenesis  Regeneration  Rhizomes  Spore Formation  Cloning 15

23. 23 1. Telomeres might be longer than normal. 2. Telomeres might be shorter than normal. 3. Telomeres might be of normal length. 4. No telomeres would be present.

24.  Binary fission - Bacteria. The circular chromosome duplicates itself and the cell splits into two identical new cells.  Budding - grow directly on the body of the parent. It eventually breaks off and establishes itself as a new, separate organism.  Regeneration - part of the parent's body breaks off and grows into a complete, new organism.  Rhizomes - Some plants (strawberries, potatoes, certain types of grass, etc) form runners that spread out from the parent plant to form plantlets at their ends. 24

25. Spore formation - fungi and some algae develop into a new organism after dispersal. Parthenogenesis - the development of an egg that has not been fertilized into an individual. Animals like most kinds of wasps, bees, and ants that have no sex

26. asexual reproduction are genetically identical copies, or clones, of the parent. Cloning of mammals Dolly the sheep

30.  unrestrained cell growth and division  can lead to tumors  second leading cause of death in the United States 30

37. Both treatments affect cells that are actively dividing. 37

38.  Unrestrained cell growth and division.  Large masses of cells called malignant tumors that can cause serious health problems.  Treatment focuses on killing or slowing the division of the cells using chemotherapy and/or radiation. 38
