Cell Cycle

2. - When a cell is damaged beyond repair, it destroys itself (pop!)
5. - The four steps that a cell goes through in order to divide. Growth, replicating DNA, growing again, and actually
6. - The part of the cell cycle that divides the chromosomes into two new identical nuclei, occurs just before the cell actually divides.
9. - 1 half of the replicated/duplicated chromosome.
11. - a growth or tumor that has cancerous cells that have the ability to spread to other parts of the body
13. - mitosis - the nucleus divides before the cell divides, so the new cells will have a complete set of genetic material.
15. - cell that has 2 complete sets of chromosomes, one set from each parent.
16. - exposure to substances (like pesticides or other mutagens) that can increase the risk of disease
17. - one cell divides into two new daughter cells
18. - abnormal masses of tissues created by uncontrolled cell growth.
19. - a tumor or growth that is not cancerous.

1. - Attach to the sister chromatids at the centromere. Pull the chromatids to opposite ends of the cell.
3. - Cells changing from immature, unspecialized cells to specialized cells based on where in the body they are.
4. - the plural for nucleus
7. - Cancer has spread to a different part of the body from where it started.
8. - A place in the cell cycle when the process can be halted until conditions are favorable.
10. - a cell that has only one set of chromosomes. These are gametes (egg or sperm cells)
12. - Either of the two cells that are made during mitosis and cytokinesis.
13. - the membrane that surrounds the nucleus of eukaryotic cells.
14. - Abnormal cell growth with the potential to invade or spread to other parts of the body.
