Across
  1. 2. Pair of organelles in animal cells from which spindle fibers grow during cell division.
  2. 3. Diploid cells that contain two sets of chromosomes and reproduce through mitosis.
  3. 7. Process by which two separate individuals combine gametes to produce young that are genetically different than their parents.
  4. 14. Structures that connect to the sister chromatids and move them around during mitosis and meiosis.
  5. 15. Cell cycle phase where the nuclear envelope disappears and the chromosomes are clearly visible in the center of the cell.
  6. 16. Structure formed after DNA replicates and two sister chromatids join together at the centromere.
  7. 17. Cell cycle phase where the sister chromatids are separated and moved to opposite ends of the cell.
  8. 18. Term given to cells that contain only one set of chromosomes.
  9. 20. Pairs of chromosomes that contain genes that code for the same traits.
  10. 21. All the chromosomes in an organism except the X and Y Chromosomes.
  11. 23. Haploid cells produced through meiosis, usually called the sperm and egg cells.
  12. 25. Process by which cells divide twice to reduce the number of chromosomes and ensure genetic variety when producing gametes.
Down
  1. 1. Process by which bacteria divide to produce two genetically identical daughter cells.
  2. 4. Cell cycle phase that occurs at the end of mitosis and meiosis, when the cytoplasm is divided and separated into two new cells.
  3. 5. Linear strand of DNA that is replicated and joins to the identical strand at the ccentromere.
  4. 6. Process by which somatic cells divide to produce two genetically identical daughter cells.
  5. 8. When chromatids fail to separate during meiosis resulting in gametes missing or having an extra chromosome.
  6. 9. Process by which a segment of one homologous chromatid breaks off and attaches to the other homologous chromatid.
  7. 10. Cell cycle phase where nuclear envelopes form around the two sets of chromatids creating two new nuclei.
  8. 11. When an individual has an extra chromosome.
  9. 12. Term given to cells that contain two sets of chromosomes.
  10. 13. Cell cycle phase that occurs in between cell division when cells grow and replicate the DNA.
  11. 19. When an individual is missing a chromosome.
  12. 22. sister chromatids line up in the middle of the cell.
  13. 24. Type of reproduction in which there is only one parent and the offspring are genetically identical to the parent.
