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