Cell Cycle

5. phase of mitosis when the nuclear envelopes reforms, the chromosomes start to uncoil, and spindle fibers disappear.
7. phase of mitosis when spindle fibers align the chromosomes along the cell's equator.
10. process by which the cell's cytoplasm divides.
11. process by which unspecialized cells develop into their mature form and function.
14. first stage of the cell cycle.
15. cell that can divide for long periods of time while remaining undifferentiated.
17. programmed cell death.
18. long, continuous thread of DNA that consists of numerous genes and regulatory information.
20. phase of interphase where DNA is synthesized or made.
21. pattern of growth, DNA replication, and nuclear division that occurs in eukaryotic cells.

1. stage of mitosis when chromatin condenses, nuclear envelope breaks down, and spindle fibers are formed.
2. broad group of proteins that stimulate cell division.
3. formed in plant cells during cytokinesis.
4. region of the chromosome where spindle fibers attach during both mitosis and meiosis.
6. having no dangerous effect on health.
8. cancerous tumor in which cells break away and spread to other parts of the body; causing harm to the organism's health.
9. one half of a chromosome is called this.
12. this is formed in an animal cell during cytokinesis.
13. common name for a class of diseases characterized by uncontrolled cell division.
16. process by which a cell divides the nucleus and its contents.
19. phase of mitosis during which sister chromatids separate and are pulled to opposite sides of the cell.
