  1. 1. unspecialized cells that retain the ability to become a wide variety of specialized cells.
  2. 5. Area where the chromatids of a chromosome are attached.
  3. 6. Programmed cell death.
  4. 9. one of a group of external regulatory proteins that stimulate the growth and division of cells.
  5. 11. Cells that are capable of developing into most, but not all, of the body's cell types.
  6. 13. The ability to sort out and use independently different parts of the body in a specific and controlled manner.
  7. 14. "The events of cell division; includes interphase, mitosis, and cytokinesis”.
  8. 16. A mass of abnormal cells that develops when cancerous cells divide and grow uncontrollably.
  9. 18. Process of reproduction involving a single parent that results in offspring that are genetically identical to the parent.
  10. 22. "Final phase of mitosis during which chromosomes uncoil, a nuclear envelope returns around the chromatin, and a nucleolus becomes visible in each daughter cell”.
  11. 23. a cell that can turn into some of the cells.
  12. 25. Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell.
  13. 26. Cell organelle that aids in cell division in animal cells only.

  1. 2. A cellular structure carrying genetic material, found in the nucleus of eukaryotic cells. Each chromosome consists of one very long DNA molecule and associated proteins.
  2. 3. stage of early development in mammals that consists of a hollow ball of cells.
  3. 4. When the chromosome align connected to the spindle fibers.
  4. 5. Process by which a cell divides into two new daughter cells.
  5. 7. one of a family of closely related proteins that regulate the cell cycle in eukaryotic cells.
  6. 8. Disorder in which some of the body's cells lose the ability to control growth.
  7. 10. Division of the cytoplasm during cell division.
  8. 12. A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents.
  9. 14. Substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones.
  10. 15. one of two identical "sister" parts of a duplicated chromosome.
  11. 17. Stem cells with the potential to differentiate into any type of cell.
  12. 19. A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, pro-metaphase, metaphase, anaphase, and telophase. Mitosis conserves chromosome number by equally allocating replicated chromosomes to each of the daughter nuclei.
  13. 20. stage of the eukaryotic cell cycle when the cell grows, synthesizes DNA, and prepares to divide.
  14. 21. An organism in the earliest stage of development.
  15. 24. Chromosomes become visible, nuclear envelop dissolves, spindle forms.
