Cell Cycle Crossword
Across
- 2. Two sets of chromosomes, one set from each parent
- 6. When a cell is not actively dividing, this is in a non-condensed form
- 13. Checks for microtubule attachment to chromosomes at kinetochores at metaphase
- 15. Most important checkpoint, checks for cell size, growth, factors, and DNA damage
- 16. A drug treatment that uses powerful chemical to kill the fast growing cells in your body
- 18. Results in 2 identical diploid daughter cells, Mitosis+Cytokinesis
- 19. Involves an internal control system that consists of cyclins and CDK's
- 20. Broken down into 5 stages (prophase,prometaphase,metaphase,anaphase,telophase/cytokinesis)
- 23. DNA wraps around these proteins giving the chromosome a compact shape
- 24. This is formed from DNA and histones combined
- 25. Enzymes that are active only when its specific cyclin is presented
- 26. Reproductive cells(eggs/sperm), haploid, divides by meiosis
- 27. Cell is split into 2 cells by cleavage furrow (animals) and cell plate forms (plants)
- 28. The longest portion of the cell cycle(90%), G1+S+G2
- 29. chromatin condenses, nuclei disappear, duplicated chromosomes appear as sister chromatids, mitotic spindle begin to form, centrosomes move away from each other
- 30. The region on each sister chromatid where they are most closely attached
Down
- 1. One set of chromosomes
- 3. Nuclear envelope fragments, microtubules enter nuclear area and some attach to kinetochores
- 4. Proteins that are synthesized and degraded at specific stages of the cell cycle
- 5. Hormones released by cells that stimulate cell growth
- 7. Cells rely on attachment to other cells or the extracellular matrix to divide
- 8. Some cells stay here forever (muscle/nerve cells), some cells can be called back into the cell cycle
- 9. Checks for completion of DNA replication and DNA damage
- 10. Centrosomes are at opposite poles, chromosomes line up at metaphase plate, microtubules attach to each kinetochore
- 11. Sister chromatids separate and move to opposite ends of cell( microtubules shortening), cell elongates
- 12. Cell surface receptors recognize contact with other cells
- 14. Proteins attached to the centromere that link each sister chromatid to the middle spindle
- 17. Two daughter nuclei form, nucleoli reappear, chromosomes become less condensed
- 21. Normal kidney function is prodominately by post-mitotic quiescent cells in the g0 phase with a low turnover. Similar to other cancers because it has mutations and doesn't follow the checkpoints
- 22. Body cells, diploid(2n), divides by mitosis
- 25. After DNA replication, chromatin condenses to form this
