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