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