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