Across
  1. 3. critical point where "stop" and "go" signals can regulate the cycle
  2. 5. one long continuous thread of DNA that consists of thousands of genes and regulatory information
  3. 6. separation of cytoplasm and 2 identical daughter cells
  4. 8. clump of cells that divide uncontrollably
  5. 9. the first stage of cell division; nuclear membrane disappears and spindle fibers form
  6. 12. second stage of cell division; spindle fibers connect to centromers
  7. 13. abnormal cells that typically remain clustered together
  8. 14. protein structure that divides genetic material in a cell
  9. 15. programmed cell death
  10. 18. third stage of cell division; sister chromatids separate pulling away from each other and become individual chromosomes
  11. 19. cell grows and makes protein
  12. 21. produce insulin to treat patients with diabetes
  13. 23. resting phase between divisions of cells
  14. 24. Cancer cells that break away from the tumor and move to other parts of the body /more tumors
  15. 26. information transferred from the cell surface to the nucleus
  16. 27. undifferentiated cells found throughout the body
  17. 28. DNA replication occurs; doubles number of chromosomes
  18. 29. changing the structure of a gene
Down
  1. 1. more cell growth and protein synthesis
  2. 2. the nuclear envelope
  3. 4. region of the condensed chromosomes that looks pinched
  4. 7. basic unit of heredity that occupies a specefic location on a chromosome
  5. 10. uncontrolled cell division
  6. 11. final phase of cell division; chromosomes decondense and nuclear membrane re-forms
  7. 12. cancer that spreads to other sites in the body by metastasis
  8. 14. 2 identical chromatids
  9. 16. organelle near the nucleus in animal cells
  10. 17. the end of the DNA molecule
  11. 20. a process that creates special structures and functions
  12. 22. cell division
  13. 25. membrane bound organelle that contains the cell's chromosomes
