  1. 4. one of two identical "sister" parts of a duplicated chromosome
  2. 5. a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes
  3. 7. a mass of abnormal cells that remain at the site of origin
  4. 8. A cell containing only one set of chromosomes (n), examples: sperm and egg
  5. 10. phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin, 2 nuclear envelopes form, nucleolus becomes visible

  1. 1. Cells that do not contain nuclei, reproduce asexually and use haploid cells
  2. 2. division of the cytoplasm to form two separate daughter cells plant cells: cell plate and animal cells: cleavage furrow
  3. 3. Cells that enclose their DNA in nuclei, reproduce both asexually and sexually, use both haploid and diploid cells
  4. 5. granular material visible within the nucleus; consists of DNA tightly coiled around proteins
  5. 6. Division of the nucleus
  6. 9. the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles
  7. 11. first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus
  8. 13. any cell of a living organism other than the reproductive cell, 2n
