Across
  1. 1. one of a group of external regulatory proteins that stimulate the growth and division of cells
  2. 5. phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
  3. 7. one of a family of proteins that regulates the cell cycle in eukaryotic cells
  4. 9. substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
  5. 12. first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
  6. 15. unstable form of a chemical element that releases radiation as it breaks down which can damage cells; used to diagnose and treat some types of cancer
  7. 17. region of a chromosome where the two sister chromatids attach
  8. 19. one of two identical "sister" parts of a duplicated chromosome
  9. 21. process by which a cell divides into two new daughter cells
  10. 23. the process of programmed cell death
  11. 24. treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing
Down
  1. 2. division of the cytoplasm to form two separate daughter cells
  2. 3. phase of mitosis in which the chromosomes line up across the center of the cell
  3. 4. type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells
  4. 6. period of the cell cycle between cell divisions
  5. 8. mass of rapidly dividing cells that can damage surrounding tissue
  6. 10. abnormal cells which divide without control and can invade nearby tissues
  7. 11. structure in an animal cell that helps to organize cell division
  8. 13. phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
  9. 14. disorder in which some of the body's cells lose the ability to control growth
  10. 16. series of events in which a cell grows, prepares for division, and divides to form two daughter cells
  11. 18. part of eukaryotic cell division during which the cell nucleus divides
  12. 20. Non-cancerous growth though it may grow larger without spreading to other parts of the body
  13. 22. network of microtubules that forms within a dividing eukaryotic cell; help to move chromosomes into the daughter cells during mitosis
