  1. 2. A disorder in which body cells lose the ability to control growth.
  2. 5. The material of which the chromosomes of organisms other than bacteria are composed. It consists of protein, RNA, and DNA.
  3. 7. A mass cancer cells form.
  4. 10. The second phase of mitosis, where the centromeres of the duplicated chromosomes line up across the center of the cell.
  5. 13. The production of genetically identical offspring from a single parent.
  6. 16. During the ___-_____, a cell grows, prepares for dividing to form two daughter cells.
  7. 19. A process of programmed cell death.
  8. 21. The second stage in the process, division of the cytoplasm, in eukaryotes.
  9. 22. The differentiated cells formed are usually limited to replacing cells in the tissue where they are found.
  10. 23. Tiny paired structures located in the centrosome.
  11. 24. The process by which a cell divides into two new daughter cells.
  12. 26. The unspecialized cells from which differentiated cells develop.

  1. 1. The first phase of mitosis, where genetic material inside the nucleus condenses and the duplicated chromosomes become visible.
  2. 3. The third phase of mitosis, where the chromosomes separate and move along spindle fibers to opposite ends of the cell.
  3. 4. A developmental stage living things like your pet dog, an earthworm or the petunia on the windowsill pass through.
  4. 6. Biologist say that the zygote is _____, able to do everything, to develop into any type of cell in the body.
  5. 7. The fourth and final stage of mitosis, where the chromosomes begin to spread out into a tangle of chromatin.
  6. 8. Cells that can develop into any of the body's cell types; generally cannot form the tissues surrounding the embryo.
  7. 9. Offspring produced by ______-__________ inherit some of their genetic information from each parent.
  8. 11. The process by which cells become specialized.
  9. 12. Simulate the growth and division of cells.
  10. 14. A protein used to regulate the cell cycle.
  11. 15. Packages of DNA Genetic information is bundled into.
  12. 17. A hollow ball of cells with a cluster of cells of the blastocyst have begun to specialize.
  13. 18. Each DNA strand in the duplicated chromosome is referred to as a _____.
  14. 20. The period of growth in between one cell division and another.
  15. 21. The duplicated strands of the DNA molecule can be seen to be attached along their length at an area called the _______.
  16. 25. The first stage of the process, division of the cell nucleus, in eukaryotes.
