  1. 4. the stage of mitosis in which the nuclear membrane breaks down.
  2. 7. a type of mitotic reproduction seen often in hydra and yeast cells.
  3. 10. the main advantage of sexual reproduction is a remixing of the DNA which creates
  4. 13. a stage of development that occurs after an embryo has been a blastocyst; the embryo is around 16 cells
  5. 15. a hollow ball of cells that is one of the first developmental stages of an animal embryo.
  6. 16. the shape of the chromosome found in a prokaryote
  7. 17. the use of chemicals that destroys cells that are dividing too fast.
  8. 18. the series of growth duplication and divisions a cell goes through.
  9. 20. microtubules from the cytoskeleton assemble to form a structure that pulls on the chromosomes, this structure is called the
  10. 21. a step in mitosis where sister chromatids separate.
  11. 23. a term that describes stem cells that will only grow into cells of a closely related type, like all blood cells.
  12. 25. adult stem cells are often harvested from bone marrow and used to treat bone marrow cancer, which is called
  13. 26. an enzyme that can move a high energy phosphate group between two molecules.
  14. 27. the scientific term for programmed cell death
  15. 29. the stage when the cell copies its nuclear DNA.
  16. 30. a group of diseases that is caused by uncontrolled cell division.
  17. 31. a protein that can turn a kinase on or off

  1. 1. the process that divides the cytosol and organelles.
  2. 2. an area at the center of the chromosome that holds two chromatids together.
  3. 3. a form of reproduction that is based on mitosis and is common in flatworms, sea stars, and planaria.
  4. 5. a term that describes a cell which can grow into any other type of cell.
  5. 6. a tumor is said to be this if its cells are likely to spread through the body.
  6. 8. a line of cancer cells that have been used for research all over the world
  7. 9. the asexual reproduction process that is used by prokaryotes.
  8. 11. a growth factor that increases the growth of red blood cells.
  9. 12. the ratio of volume and this value controls how large the cell becomes.
  10. 14. a section of DNA that controls the rate of the cell cycle
  11. 19. there are three of these stages, each one involves the cell growing.
  12. 22. a small protein that is used to wrap the DNA in an organized way is called a(n)
  13. 24. a single monomer of deoxyribonucleic acid is known as ___.
  14. 28. a unique type of body cell that can divide and renew itself for long periods of time.
