Cell Cycle

2. holds sister chromatids together.
6. phase of the cell cycle during which chromatin condenses into chromosomes.
7. uncontrolled cell division.
8. phase of the cell cycle during which chromosomes line up in the middle of the cell.
10. produces the spindle fibers in animal cells.
13. the stage of the cell or nucleus when it is not in mitosis?
15. phase of interphase during which DNA replicates.
16. the stage of the cell or nucleus when it is not in mitosis.
18. is a stage in the eukaryotic cell cycle at which the cell examines internal and external cues.
19. the location of DNA in all eukaryotic cells.

1. is a double membrane that encloses the cell nucleus.
3. the second growth period of the cell cycle following DNA replication and preceding prophase, during which the cell forms the materials that make up the spindle.
4. network of microtubules that move the chromosomes in a cell.
5. phase of the cell cycle during which the cleavage furrow forms(in animal cells) and two identical daughter cells are produced.
9. phase of the cell cycle during which chromosomes begin to unwind into chromatin: nuclear envelope reforms.
11. division of the nucleus; consists of four stages(prophase, metaphase, anaphase, telophase).
12. the ability of a cell to receive, process, and transmit signals with its environment and with itself.
14. phase of the cell cycle during which the sister chromatids separate and move to opposite poles.
17. occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene.
