  1. process by which a cell divides into two daugher cells
    cell division
  2. part of eukaryotic cell divisions during which the cell nucleus divides
    mitosis
  3. division of the cytoplasm during cell division
    cytokinesis
  4. one of the two identical "sister" parts of a duplicated chromosome
    chromatid
  5. area where the chromatids of a chromosome are attached
    centromere
  6. period of the cell cycle between cell divisions
    interphase
  7. 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
    prophase
  8. second phase of mitosis, during which the chromosomes line up across the center of the cell
    metaphase
  9. the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles
    anaphase
  10. fourth and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material
    telophase
  11. series of events that cells go through as they grow and divide
    cell cycle
  12. one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope

    cancer
  16. term used to refer to chromosomes that each have a corresponding chromosome from the opposite sex-parent
    homologous
  17. term used to refer to a cell that contains both sets of homologous chromosomes
    diploid
  18. term used to refer to a cell that contains only a single set of chromosomes and therefore only a single set of genes
    haploid
  19. process by which the number of chromosomes per cell is cut in half through separation of homologous chromosomes in a diploid cell.
    meiosis
  20. structure contianing 4 chromoatids that form during meiosis
    tetroid
  21. process in which homologous chromosomes exchange portions of their chromatids during meiosis
    crossing-over
