Across
  1. 2. DNA replication occurs to double the amount in preparation for Mphases
  2. 3. the complete set of each unique chromosome, one chromosome from each homologous pair
  3. 5. a protein complex that hols sister chromatids together
  4. 10. centromere placement close to the end
  5. 11. centrioles reach the poles of the cell, chromosomes are clear structures with spindle fibres connect to the kinetichores
  6. 14. a constricted region on the chromosome, a part that pinches in
  7. 15. a pair of centrioles with spindle fibres that forms the spindle apparatus important to movement in mitosis and meiosis
  8. 17. monitors cells size and DNA integrity
  9. 18. centromere placement at the end
  10. 21. between middle and end centromere placement
  11. 22. sister chromatids reach the poles, karyokinesis complete, cleavage begins resulting in two daughter cells
  12. 23. centromeres split and sister chromatids migrate to poles of cell being pulled by spindle fibres
  13. 24. a protein complex in the dentromeric region that protects cohesin from being degraded b a separate enzyme
  14. 25. a type of cytokinesis in animals cells where constriction occurs until two daughter cells are pinched off
  15. 26. in plant cells, it is cytokinesis where a cell plate forms on the imaginary metaphase plate and grows into the cell wall, dividing the two daughter cells
Down
  1. 1. a complex structure in animals cells and some plant cells
  2. 3. chromosomes that have identical loci along their length, from biparental inheritance
  3. 4. preparation for mitosis
  4. 6. nuclear division, dividing the genetic material
  5. 7. dividing the cytoplasm to two daughter cells, organelles are synthesized de novo
  6. 8. if spindle assembly and the attachment to the kinetochores is wrong, mitosis stops
  7. 9. when the organism has two sets of chromosomes (homologous pairs of chromosomes) one maternal and one paternal
  8. 12. middle centromere placement
  9. 13. shugoshin degrades and cohesin can be cleaved, letting sister chromatids pull apart
  10. 16. chromosomes line up along an imaginary plates as they are pulled by spindle fibres
  11. 17. checks for properly replicated DNA
  12. 19. occurs post-division where cells grow to appropriate size, may enter G0 phase
  13. 20. chromosomes coil and condense, centrioles divide and move apart
