Across
  1. 1. division of genetic material
  2. 8. maternal and paternal copies of same chromosome
  3. 10. also known as G0, where cells often pause (potentially for years!) before DNA replication
  4. 11. division of the cytoplasm in a plant cell
  5. 14. requires duplication of genome, accurate segregation (separation), and division of cellular contents
  6. 16. ordered display of all chromosomes in an in individual organism
  7. 17. attachment site for microtubules
  8. 20. division of the cytoplasm in an animal cell, involves actin filaments
  9. 22. phase of mitosis in which microtubules attach to sister chromatids
  10. 24. how bacteria divide
  11. 25. first stage of bacterial division
  12. 26. phase of mitosis in which chromosomes are pulled to opposite poles
  13. 27. normal cellular genes that become oncogenes when mutated
  14. 28. cell cycle process is checked for accuracy and can be halted here if any errors
Down
  1. 2. phase within cell cycle that consists of G1, S, and G2
  2. 3. phase of mitosis in which chromosomes condense and become visible
  3. 4. both copies of this gene type must lose function for cancerous phenotype to develop
  4. 5. replication begins here, and proceeds in two directions
  5. 6. phase of mitosis in which all chromosomes are aligned at equator of cell
  6. 7. second stage of bacterial division
  7. 9. replicated chromosomes, held together at centromeres
  8. 12. phase of mitosis in which nuclear envelopes reform and chromosomes decondense
  9. 13. complex of DNA and protein that make chromosomes
  10. 15. chromatin in the nondividing nucleus that will be expressed
  11. 18. one complete set of chromosomes necessary to define an organism
  12. 19. complex of DNA and histone proteins, promote and guide coiling of DNA
  13. 21. division of the cytoplasm
  14. 23. third (final) stage of bacterial division, involves septation
