Across
  1. 5. a photographic representation of the chromosomes within a cell
  2. 6. the region that joins the two sister chromatids, or each half of the chromosome
  3. 7. structures that contain genetic material
  4. 10. the stage of mitosis or meiosis in which the nuclear membrane disintegrates and the centrioles reach the poles of the cell wh
  5. 12. the stage in mitosis or meiosis following metaphase in which the daughter chromosomes move away from each other to opposite ends of the cell
  6. 13. the place on either side of the centromere to which the spindle fibers are attached during cell division
  7. 16. the physical location of a gene
  8. 18. true nucleus, containing nucleus
  9. 19. primary purpose of it is to divide one cell nucleus into two nuclei
Down
  1. 1. the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle
  2. 2. the division of the cell cytoplasm that usually follows mitotic or meiotic division of the nucleus
  3. 3. prenucleus, without nucleus (bacteria and archaea)
  4. 4. the region in the prokaryotic cell (irregular shape) that contains the main DNA material
  5. 7. the field of genetics that involves the microscopic examination of chromosomes
  6. 8. highly specialized compartment within the internal membrane with specific functions
  7. 9. G1, S and G2 phases
  8. 11. the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands
  9. 14. a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells
  10. 15. one of two identical halves of a replicated chromosome
  11. 17. the chromosomes reach the poles and nuclear envelopes appear. When this phase is over, cell division is complete
