Across
  1. 4. structure in an animal cell that helps to organize cell division
  2. 6. phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
  3. 7. process of reproduction involving a single parent that results in offspring that are genetically identical to the parent
  4. 8. a threadlike structure within the nucleus that contains genetic information that is passed on from one generation to the next
  5. 10. one of a family of proteins that regulates the cell cycle in eukaryotic cells
  6. 11. disorder in which some of the body's cells lose the ability to control growth
  7. 15. phase of mitosis in which the chromosomes line up across the center of the cell
  8. 17. one of two identical "sister" parts of a duplicated chromosome
  9. 19. one of a group of external regulatory proteins that stimulate the growth and division of cells
  10. 21. an abnormal, but non-cancerous collection of cells which do not invade other sites of the body
  11. 22. type of reproduction in which cells from two parents unite to form the first cell of a new organism
  12. 23. part of eukaryotic cell division during which the cell nucleus divides
  13. 24. the process of programmed cell death
  14. 25. series of events in which a cell grows, prepares for division, and divides to form two daughter cells
Down
  1. 1. (M phase) process by which a cell divides into two new daughter cells
  2. 2. first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
  3. 3. phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
  4. 4. region of a chromosome where the two sister chromatids attach
  5. 5. 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. 9. abnormal cells which divide without control and can invade nearby tissues
  7. 11. treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing
  8. 12. type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells
  9. 13. division of the cytoplasm to form two separate daughter cells
  10. 14. network of microtubules that forms within a dividing eukaryotic cell; help to move chromosomes into the daughter cells during mitosis
  11. 16. mass of rapidly dividing cells that can damage surrounding tissue
  12. 18. period of the cell cycle between cell divisions
  13. 20. a substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
