Across
  1. 2. where the chromosomes are aligned, midway between two poles of a cell
  2. 4. where the sister chromatids are bound together, found in condensed chromosomes
  3. 6. stage where chromosomes arrive at opposite poles, decondense, and are surrounded by a new nuclear envelope
  4. 7. haploid reproductive cell
  5. 8. third phase of interphase, cell undergoes final preparations for mitosis
  6. 11. mutated gene in the positive regulation o the cell cycle
  7. 15. unit of heredity, a sequence of DNA that codes for a protein
  8. 16. first phase in the cell cycle, preparation for mitosis
  9. 19. stage where chromosomes are aligned at the metaphase plate
  10. 20. the sequence that the cell passes through, one cell division to the next
  11. 21. a single DNA molecule of two strands of duplicated DNA
  12. 22. formed during cytokinesis, a ____ is formed and fused to the metaphase plate which helps form the cell walls of two daughter cells
  13. 24. first phase of interphase, cell is not preparing to divide
  14. 25. containing two sets of chromosomes (2n)
  15. 28. protein found in chromatin, associates with DNA to form nucleosomes
  16. 29. synthesis stage of interphase where DNA replication happens
  17. 30. division of the cytoplasm
  18. 31. composed of microtubules that determines the movement of chromosomes during mitosis
Down
  1. 1. gene that when mutated becomes an oncogene
  2. 3. segment of DNA that codes for regulator proteins that prevent the cell from undergoing uncontrolled division
  3. 5. formed at the connection between two splitting cells
  4. 9. total genetic information of a cell
  5. 10. stage where chromosomes condense and the mitotic spindle starts to form
  6. 12. protein associated with the centrosome of the chromatid, attracts and dins spindles during prometaphase stage where the nuclear membrane breaks down and mitotic spindle fibers attract to kinetochores
  7. 13. microtubule structure at the center of an animal cells centrosome
  8. 14. containing one set of chromosomes (n)
  9. 15. second phase of interphase, centered on cell growth during mitosis
  10. 17. regulatory protein for cell growth that monitors DNA damage, halt cell cycle if there is DNA damage and may induce apoptosis
  11. 18. monitors the readiness of a cell to advance through the stages in the cell cycle
  12. 23. period of the cell cycle where cells are duplicated
  13. 26. a phase in mitosis where the sister chromatids separate from each other
  14. 27. location of a gene on a chromosome
