Cell Cycle

5. Condensed chromatin
11. Checks for cell size, growth factors, and DNA damage
12. Longest portion of cell cycle- contains G1, S, and G2
14. Region on chromatid where they are most closely attached
16. Chromatin condenses, mitotic spindle forms, centrosomes move away from each other
17. Hormones released by cells that stimulate cell growth-CDKs activated leading to progression through cycle
18. Body cells-contain diploid cells-divide by mitosis
20. Protein that provides structural support to a chromosome
22. Two nucleus formed in preparation for cytoplasm to split
23. Cells rely on attachment to other cells of matrix to divide
25. One set of chromosomes

1. Proteins attached to centromere to link chromatid to mitotic spindle
2. Repeating unit of eukaryotic chromatin
3. A way to prevent cancer, by killing the
4. Similar to all cancers because it has DNA mutations- don't follow checkpoints, immortal, and evade apoptosis.
5. Has specific regulatory effect-these phosphorylate target proteins, which help regulate events in the cell cycle
6. Includes Mitosis, Cytokinesis, and results in 2 identical diploid cells
7. Material are composed as DNA/RNA
8. Chromatids separate and move to opposite sides of cell, cell then elongates
9. Nuclear envelope fragments, and microtubules enter nuclear area and some attach to kinetochores
10. Centrosomes at opposite poles, line up at metaphase plate, and microtubules attached to each kinetochore
11. Reproductive cells-contain haploid-divide by meiosis
13. Cells are split into 2 cells by cleavage furrow(animals), and cell plate forms (plant)
15. Synthesized and degraded at specific stages of the cell cycle
17. Checks for completion of DNA replication and DNA damage-If good, then moves to mitosis
19. Two sets of chromosomes, one set from each parent
21. growing cells
24. Some stay here forever, and some can be called back into the cell
