  1. 1. Disorder in which some of the body's cells lose the ability to control growth
  2. 3. Threadlike structure of DNA and protein that contains genetic information in eukaryotes, chromosomes are found in the nucleus;in prokaryotes, they are found in the cytoplasm
  3. 4. Division of the cytoplasm to form two separate daughter cells
  4. 7. Reproduction involving the union of gametes
  5. 9. Region of a chromosome where the two sister chromatids attach
  6. 10. Substance found in eukaryotic chromosomes that consist of DNA tightly coiled around histones
  7. 11. Series of events in which a cell grows, prepares for division, and divides to form two daughter cells
  8. 12. Developing stage of a multicellular organism
  9. 13. Cells that are able to develop into any type of cell in the body

  1. 1. The division of a cell into two daughter cells with the same genetic material
  2. 2. One of a group of external regulatory proteins that stimulate the growth and division of cells
  3. 5. Cell with limited potential to develop into many types of differentiated cells
  4. 6. Process in which cells become specialized in structure and function
  5. 8. One of a family of proteins that regulates the cell cycle in eukaryotic cells
  6. 14. Period of the cell cycle between cell division
  7. 15. Process of programmed cell death
  8. 19. Phase of mitosis in which the chromosomes line up across the center of the cell
  9. 21. First and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
  10. 23. Cells that are capable of developing into some but not all the body's cells
  11. 25. Part of eukaryotic cell division during which the cell nucleus divides
