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