Across
  1. 7. process by which cells become specialized in structure and function
  2. 13. part of eukaryotic cell division during which the cell nucleus divides
  3. 16. region of a chromosome in which the two sister chromatids attach
  4. 17. process in reproduction involving a single parent that result in offspring that are genetically identical to the parent
  5. 19. developing stage of a multicellular organism
  6. 22. mass of rapidly dividing cell that can damage surrounding tissue
  7. 23. type of reproduction in which cells from two parents unite to form the first cell of a new organism
  8. 25. one of two identical “sister” parts of a duplicated chromosome
  9. 26. process of programmed cell death
  10. 27. phase of mitosis in which the chromosomes line up across the center of the cell
Down
  1. 1. process by which a cell divides into two daughter cells
  2. 2. cells that are capable of developing into most, but not all, of the body’s cell types
  3. 3. cell with limited potential to develop into many types of differentiated cells
  4. 4. factor one of a group that of external regulatory proteins that stimulate the growth and division of cells
  5. 5. stage of early development in mammals that consists of a hollow ball of cells
  6. 6. phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
  7. 8. cells that are able to develop into any type of cell found in the body (including the cells that make up the extra-embryonic membranes and placenta)
  8. 9. one of a family of proteins that regulated the cells cycle in eukaryotic cells
  9. 10. period of the cell cycle between cell divisions
  10. 11. structure in an animal cells that helps to organize cell division
  11. 12. substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
  12. 14. unspecialized cell that can rise to one or more types of specialized cells
  13. 15. series of events in which a cell grows, prepares for division, and divides to form two daughter cells
  14. 18. division of the cytoplasm that to form two separate daughter cells
  15. 20. disorder in which some of the body’s cells lose the ability to control growth
  16. 21. threadlike structure of DNA and proteins that contain genetic information; in eukaryotes, chromosomes are found in the nucleus; in prokaryotes, they are found in the cytoplasm
  17. 24. first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
  18. 26. phase in mitosis in which the chromosomes separate and move to opposite ends of the cell
