Across
  1. 5. region of a chromosome where the two sister chromatids attach
  2. 7. substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
  3. 9. cell with limited potential to develop into many types of differentiated cells
  4. 14. phase of mitosis in which the chromosomes line up across the center of the cell
  5. 16. the process of programmed cell death
  6. 17. the presence of cancerous cells that have the ability to spread to other sites in the body (metastasize) or to invade nearby (locally) and destroy tissue
  7. 18. type of reproduction in which one parent cell produces two identical offspring (daughter cells)
  8. 19. first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
  9. 21. the development of secondary malignant growths at a distance from a primary site of cancer
  10. 23. type of reproduction in which cells from two parents unite to form the first cell of a new organism
  11. 27. disorder in which some of the body's cells lose the ability to control growth
  12. 28. phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
  13. 30. process in which cells become specialized in structure and function
  14. 32. threadlike structure within the nucleus that contains genetic information that is passed on from one generation to the next
  15. 33. one of two identical "sister" parts of a duplicated chromosome
  16. 34. agent with the capacity to cause cancer in humans
Down
  1. 1. the treatment of disease, especially cancer, using X-rays or similar forms of radiation.
  2. 2. drug treatment that uses powerful chemicals to kill fast-growing cells in your body
  3. 3. period of the cell cycle between cell divisions in which the cell grows
  4. 4. a fertilized egg
  5. 6. division of the cytoplasm to form two separate daughter cells
  6. 8. cells that are capable of developing into most, but not all, of the body's cell types
  7. 10. tumor, or growth that is not cancerous (does not spread into nearby tissues)
  8. 11. treatment that uses certain parts of a person's immune system to fight diseases such as cancer
  9. 12. any change in the DNA sequence
  10. 13. cells that are able to develop into any type of cell found in the body (including the cells that make up the extraembryonic membranes and placenta)
  11. 15. growth of new blood vessels that tumors need to grow
  12. 20. type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells
  13. 22. phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
  14. 24. one of a family of proteins that regulates the cell cycle in eukaryotic cells
  15. 25. unspecialized cell that can give rise to one or more types of specialized cells
  16. 26. stage of early development in mammals that consists of a hollow ball of cells
  17. 29. series of events in which a cell grows, prepares for division, and divides to form two daughter cells
  18. 31. developing stage of a multicellular organism
