25 Questions

1. Could be an example of cases where ancestral mechanisms have remained relatively unchanged over evolutionary time. The nuclear envelope remains intact during cell division and the chromosomes attach to the nuclear envelope. Microtubules pass through

2. The reproduction of cells

3. A part of the cell cycle. Often accounts for about 90% of the cell cycle. In this phase - the cell grows and copies its chromosomes in preparation for cell division.

4. A protein that promotes mitosis. Often called a growth factor though.

5. A specific protein release by certain cells that stimulates other cells to divide.

6. Reproductive cells--sperm and egg cells. Have half as many chromosomes as somatic cells. Have one set of 23 chromosomes in humans.

7. A type of unicellular protist. Mostly marine plankton.

8. Fourth phase of mitosis. The shortest stage of mitosis. Begins with the two sister chromatids of each pair being pulled apart--each becoming a full fledged chromosome. The two liberated chromosomes begin moving towards opposite ends of the cell - as

9. A type of cell division that prokaryotes (bacteria and archaea) undergo to reproduce.

10. The spread of cancer cells to locations distant from their original site.

11. A phenomenon in which crowded cells stop dividing. When a cell population reaches a certain density - the availability of nutrients becomes insufficient to allow continued cell growth and division. Not exhibited in cancer cells.

12. What eukaryotic chromosomes are made of. A complex of DNA and associated protein molecules.

13. No cleavage furrow. During telophase - vesicles derived from the Golgi apparatus move along microtubules to the middle of the cell - where they coalesce - producing the cell plate.

14. All body cells except the reproductive ones. The nuclei of human somatic cells contain 46 chromosomes made up of two sets of 23 - one set inherited from each parent.

15. First phase of interphase. Major period of cell growth. Most variable length in length for all the phases in different types of cells.

16. The last phase of interphase - occurring after the S phase. Cell continues to grow but also completes preparations for cell division. In this phase - chromosomes that duplicated during S phase cannot be seen individually because they have not condens

17. Third phase of mitosis. The longest stage of mitosis (~20mins). The centrosome are now at opposite ends of the cell. The chromosomes convene on the metaphase plate. For each chromosome - the kinetochores of the sister chromatids are attached to kinet

18. First phase of Mitosis. The chromatin fibers become more tightly coiled - condensing into discrete chromosomes observable with a light microscope. Nucleoli disappear. Each duplicated chromosome appears as two identical sister chromatids joined togeth

19. Begins to form in the cytoplasm during prophase. Consists of fibers made of microtubules - centrosomes and associated proteins. While it assembles - other microtubules of the cytoskeleton partially disassemble - probably providing the material used t

20. Each duplicated chromosome has two sister chromatids. Each contain an identical DNA molecule and are initially attached by adhesive proteins all along their lengths. Are most closely attached to one another at the centromere.

21. A radial array of short microtubules that extend from each centrosome. (Do not connect to kinetochore.)

22. Prophase - prometaphase - metaphase - anaphase - and telophase.

23. Second phase of mitosis. The nuclear envelope fragments. The microtubules of the spindle can now invade the nuclear area and interact with the chromosome - which have become even more condensed. Microtubules extend from each centrosome towards the m

24. Usually immediately follows mitosis. The division of the cytoplasm of a cell-where one cell becomes two - each genetically equivalent to the parent cell. Involves the formation of a cleavage furrow - which pinches the cell in two.

25. Abnormal cells remain at the original sight after transformation (the process that converts normal cells to cancer cells). Usually do not cause serious problems and can be removed by surgery.
