  1. 3. Copying process by which a cell duplicates its DNA
  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. 6. Is a eukaryotic cell formed by the fertilization between a female gamete and a male gamete.
  4. 8. Chromatin condenses into chromosomes to prepare for chromosome division, the nucleus breaks down so the chromosomes can move around the cell, and the centrioles move apart and the mitotic spindle forms.
  5. 11. Cells that result from the division of a single parent cell.
  6. 12. The process of change that occurs during an organism’s life for growth and repair in multicellular organisms and reproduction in unicellular organisms.
  7. 13. The regular sequence of growth and division that cells undergo.
  8. 15. Is where the cell grows and prepares for the mitotic phase.
  9. 16. Spindle fibers dissolve and nucleus reforms around each set of daughter chromosomes.
  10. 18. Cell elongates and sister chromatids are pulled apart toward the poles.
  11. 21. Exactly the same

  1. 1. The process of developing or maturing.
  2. 2. Somatic cell; any biological cell forming the body of an organism; that is, in a multicellular organism, any cell other than a gamete, germ cell, gametocyte or undifferentiated stem cell.
  3. 3. Make good (such as damage) by fixing or repairing it.
  4. 4. Division of the cytoplasm occurs to form two separate daughter cells.
  5. 7. The process of change that occurs during an organism’s life to produce a more complex organism.
  6. 9. A cell that is the source of other cells.
  7. 10. The cell division process that creates egg and sperm cells.
  8. 12. Chromosomes line up in the middle of the cell.
  9. 14. A complex molecule containing the genetic information that makes up the chromosomes.
  10. 17. A cell having only one set of chromosomes.
  11. 19. Gamete cell (ova in females; sperm in males); have only half the number of chromosomes that other cells (body cells) have
  12. 20. Describes a cell or nucleus which contains two copies of genetic material, or a complete set of chromosomes
