Across
  1. 4. - something that causes a mutation
  2. 6. - a single celled organism that does not have a nucleus
  3. 11. - the stage in mitosis where two nuclei begin to form
  4. 13. - is what DNA is organized into
  5. 14. fission - the cell cycle for prokaryotic cells, consists of DNA replication, and cytokinesis.
  6. 15. - the stage before mitosis and where DNA replicates
  7. 16. phase - last phase of of interphase where cells get analyst bits of growth done before division
  8. 20. phase - follows the stages of mitosis in order and finish with cytokinesis
  9. 22. plate - a plate that is built between two plant daughter cells to separate them during cytokinesis
  10. 23. cells - a pluripotent cell that is part of the embryonic development
  11. 27. - It is programmed cell death, the cell is broken down and its parts are recycled.
  12. 31. - they anchor the spindle fibers to them
  13. 32. - the stage of mitosis where the sister chromatids start to get pulled to their assigned poles
  14. 33. cells - specialized cells with specific functions
  15. 34. chromatids - after DNA replication there is a double chromosome consisting of….
  16. 35. of cancer - STEAL nutrients from the healthy cells, SPREADS to multiple locations in the body, and tumors take up SPACE and interrupt organs functions
  17. 36. - consist of one chromatin
  18. 39. fibers - protein structures that form in the cell during mitosis to pull apart the chromosomes
  19. 40. - cells that can differentiate to become any body cell
  20. 42. - all of the chromosomes combined
Down
  1. 1. - DNA packed into chromosomes consists of one of these.
  2. 2. - a multicellular organism that does have a nucleus
  3. 3. - the double helix proteins.
  4. 4. - cells that can only differentiate to become a limited range of cells
  5. 5. phase - first phase in interphase where cells grow and do normal functions
  6. 7. factor - a possible leading cause to cancer or any disease
  7. 8. - a change in the DNA code that is not fixed
  8. 9. - a mass of cells created from continuous cell division
  9. 10. - tumor that is harmless and does not spread
  10. 12. - a process where a cell divides into two identical daughter cells that includes four steps (Prophase, Metaphase, Anaphase, and Telophase)
  11. 13. - beings during telophase and where the cytoplasm beings to split
  12. 17. - cancerous tumor that grows and spreads
  13. 18. cycle - the cycle in which a cell undergoes DNA replication and cell division
  14. 19. pluripotent stem - a cell that is artificially created in a lab from fat, skin, or fibroblasts, into pluripotent cells
  15. 21. - the stage in mitosis where there DNA beings to pack into chromosomes
  16. 24. spindle - the centriole and the spindle fibers
  17. 25. - a disease caused by uncontrolled division of abnormal cells in a part of the body
  18. 26. chromatin - where a nucleus looks darker, larger, or clumped together
  19. 28. - the longest phase of the cell cycle and happens when the cell is not dividing. DNA is in the form of chromatin and replication takes place
  20. 29. - found in eukaryotic cells and contains DNA
  21. 30. - the stage of mitosis where all the chromosomes line up in the middle of the cell
  22. 36. - the sister chromatids are held together at this point to keep them together
  23. 37. - pieces of a malignant tumor breaks off and moves elsewhere in the body
  24. 38. phase - second phase of interphase where cells undergo DNA replication
  25. 41. cells - a multipotent cell that doesn’t have a specific function yet
