Across
  1. 2. One of two identical “sister” parts of a duplicated chromosome
  2. 5. Type of reproduction in which cells from two parents unite to form the first cell of a new organism
  3. 6. Stage of early development in mammals that consists of a hollow ball of cells
  4. 9. Phase of mitosis in which the chromosomes line up across the center of the cell
  5. 10. Cells that are able to develop into any type of cell found in the body (including cells that make up the extraembryonic membranes and placenta)
  6. 11. First and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
  7. 12. Disorder in which some of the body’s cells lose the ability to control growth
  8. 13. Period of the cell cycle between cell divisions in which the cell grows
  9. 14. Mass of rapidly dividing cells that can damage surrounding tissue
  10. 17. Phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
  11. 19. Unspecialized cell that can give rise to one or more types of specialized cells
  12. 21. Division of the cytoplasm to form two separate daughter cells
  13. 22. Process in which cells become specialized in structure and function
  14. 23. One of a group of external regulatory proteins that stimulate the growth and division of cells
  15. 25. Process of development during which embryonic cells specialize and diverse tissue structures arise
Down
  1. 1. Cells that are capable of developing into most, but not all, of the body’s cell types
  2. 3. Process of reproduction that involves a single parent that results in offspring that are genetically identical to the parent
  3. 4. The process of programmed cell death
  4. 7. Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
  5. 8. Phase of mitosis in which the chromosomes line up across the center of the cell
  6. 9. Cell with limited potential to develop into many types of differentiated cells
  7. 12. Substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
  8. 15. Series of events in which a cell grows, prepares for division, and divides to form two daughter cells
  9. 16. One of a family of proteins that regulates the cell cycle in eukaryotic cells
  10. 18. Developing stage of a multicellular organism
  11. 20. Part of eukaryotic cell division during which the cell nucleus divides
  12. 21. Threadlike structure within the nucleus that contains genetic information that is passed from one generation to the next
  13. 24. Process in which cells divide into new daughter cells
