Across
  1. 2. Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
  2. 8. Clusters of DNA, RNA, and proteins in the nucleus of a cell
  3. 10. Chromosomes line up in the middle of the cell
  4. 12. Chromosomes become visible, nuclear envelope dissolves, spindle forms
  5. 13. two identical chromosomes that split and contain the same genetic material
  6. 14. A complex molecule containing the genetic information that makes up the chromosomes.
  7. 15. reproductive cells
  8. 17. The area of the cell membrane that pinches in and eventually separates the dividing cell
  9. 19. part of eukaryotic cell division during which the cell nucleus divides
  10. 21. threadlike structures made of DNA molecules that contain the genes
Down
  1. 1. A double membrane across the midline of a dividing plant cell, between which the new cell wall forms during cytokinesis.
  2. 3. proteins that regulate the timing of the cell cycle in eukaryotic cells
  3. 4. any malignant growth or tumor caused by abnormal and uncontrolled cell division
  4. 5. series of events that cells go through as they grow and divide
  5. 6. After the chromosome separates, the cell seals off, Final Phase of Mitosis.
  6. 7. (genetics) an organism or cell having two sets of chromosomes or twice the haploid number
  7. 9. (genetics) an organism or cell having only one complete set of chromosomes
  8. 11. period of the cell cycle between cell divisions
  9. 15. growth
  10. 16. Cell division that produces reproductive cells in sexually reproducing organisms
  11. 18. second growth
  12. 20. body cells
