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