  1. 1. Substances that are known to produce or promote the development of cancer cells
  2. 3. The regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells
  3. 4. Not harmful (Cancer cells stay together instead of breaking apart and spreading)
  4. 6. One long, continuous thread of DNA that consists of numerous genes along with regulatory information
  5. 9. When cancer cells spread to other sites in the body by metastasis
  6. 11. Groups of cells that work together to perform a similar function
  7. 13. A unique type of body cell that can divide and renew themselves for long periods of time and remain undifferentiated in form, and differentiate into a variety of specialized cell types
  8. 14. The ends of DNA molecules that are made of repeating nucleotides that do not form genes
  9. 15. The first phase of mitosis when chromosomes become visible as paired chromatids and the nuclear envelope disappears
  10. 16. Some of the cancer cells break away from the mass of cancer cells
  11. 19. A protein that provides structural support to a chromosome
  12. 20. The final phase of cell division in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed
  13. 22. Broad groups of proteins that stimulate cell division
  14. 24. A region of the condensed chromosome that looks pinched
  15. 26. One half of a duplicated chromosome
Down
  1. 2. The process by which a cell becomes specialized for a specific structure or function during multicellular development
  2. 5. Programmed cell death
  3. 7. Organs that carry out similar functions
  4. 8. The third stage of mitosis in which all genetic material is condensed into chromosomes
  5. 10. The complex of protein and DNA that makes up the chromosome
  6. 12. The production of offspring from a single parent and does not involve the joining of gametes
  7. 17. The fourth phase of mitosis that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells
  8. 18. The asexual reproduction of a single-celled organism by division into two roughly equal parts
  9. 21. The process that divides the cell cytoplasm
  10. 23. The division of the cell nucleus and its contents
  11. 24. Uncontrolled cell division
  12. 25. Group of tissues that work together to perform a specific function
