Across
  1. 2. substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
  2. 5. cells with limited potential to develop into many types of differentiated cells
  3. 7. process by which cells become specialized in structure and function
  4. 9. threadlike structure of SNA and protein that contains genetic information
  5. 11. structure of an animal cell that helps to organize cell division
  6. 12. first and longest phases of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
  7. 15. phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
  8. 17. region of a chromosome in which the two sister chromatids attach
  9. 18. one of two identical “sister” parts of a duplicated chromosome
Down
  1. 1. unspecialized cell that can give rise to one or more types of specialized cells
  2. 3. stage of early development in mammals that consists of a hollow ball of cells
  3. 4. phase of mitosis in which the chromosomes line up across the center of the cell
  4. 6. part of eukaryotic cell division during which the cell nucleus divides
  5. 8. process of programmed cell death
  6. 10. mass of rapidly dividing cells that can damage surrounding tissue
  7. 13. phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
  8. 14. period of the cell cycle between cell divisions
  9. 16. division of the cytoplasm to form two separate daughter cells
