Across
  1. 3. Substance that causes cancer; chemicals that mutate DNA.
  2. 5. Production of offspring inherit some of their genetic information from each parent.
  3. 6. Threadlike structure of DNA and protein that contains genetic information.One long thread of DNA that is tightly coiled in the nucleus.
  4. 8. Protein that regulate the timing of the cell cycle.
  5. 9. Protein that stimulates the GROWTH and division of cells during the cell cycle.
  6. 10. Mass of cancer cells that can be malignant (spreads) or benign (remains at original site).
  7. 12. One of two identical “sister” parts of a duplicated chromosome.Half of a chromosome.
  8. 13. First main part of the cell cycle consisting of G1, S, G2. Period of cell growth, replication of DNA, and preparation for division.
  9. 15. First phase of mitosis in which the cell’s genetic material condenses into chromosomes; nucleus disappears, and the spindle apparatus forms.
  10. 17. Center of a chromosome where the two sister chromatids attach.
  11. 18. Programmed cell death that happens when a cell recognizes it isn’t functioning properly.
  12. 21. Production of genetically identical offspring from a single parent.
  13. 23. Organelle in an animal cell that helps to organize cell division.
  14. 24. Series of events in which cells grow, prepare for division, and divide to form two daughter cells. Consists of 3 main parts that continually repeat in eukaryotic cells.
Down
  1. 1. Unspecialized cells that can develop into specialized cells when under the right conditions.
  2. 2. Process in which cells become specialized into DIFFERENT types of cells.
  3. 4. Second main part of the cell cycle which involves the division of the nucleus.
  4. 6. Relaxed form of DNA in the cell’s nucleus; DNA and proteins.Looks like spaghetti :).
  5. 7. Second phase of mitosis in which chromosomes line up across the MIDDLE of the cell.
  6. 11. Process by which an entire cell divides into two new daughter cells.
  7. 14. Early developmental stage which eventually produces an adult organism.
  8. 16. Third phase of mitosis in which sister chromatids are pulled apart & move to opposite poles of cell.
  9. 19. Third main part of the cell cycle that involves the division of the cytoplasm which produces two new daughter cells.
  10. 20. Fourth and final phase of mitosis in which the chromosomes are at the poles and they relax to form chromatin; nuclear membranes and nucleoli reappear; spindle apparatus breaks down.
  11. 22. Disorder caused by uncontrolled growth & division of cells; failure in regulation of the cell cycle.
