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