  1. 3. uncontrolled growth and division of cells that can be caused by changes in control of the cell cycle and also may be caused by environmental factors
  2. 4. relaxed form of DNA in the nucleus of a cell
  3. 5. process of cellular reproduction, occurring in three main stages – interphase (growth), mitosis (nuclear division), and cytokinesis (cytoplasm division)
  4. 7. one of the specific proteins that regulate the cell cycle
  5. 9. third main stage of the cell cycle, during which the cell’s cytoplasm divides, creating a new cell
  6. 10. repeating subunit of nucleic acid formed from a simple sugar, a phosphate group, and a nitrogenous base
  7. 13. first stage of mitosis, during which the cell’s chromatin condenses into chromosomes
  8. 14. last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided
  9. 16. cell structure that joins two sister chromatids
  10. 17. third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell.
  11. 18. second main stage of the cell cycle during which the cell’s replicated DNA divides and two genetically identical diploid daughter cells are produced
Down
  1. 1. second stage of mitosis in which motor proteins pull sister chromatids to the cell’s equator
  2. 2. enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle
  3. 6. first stage of the cell cycle, during which a cell grows, matures, and replicates its DNA
  4. 8. DNA-containing structure that carries genetic material from one generation to another
  5. 11. structure that contains identical DNA copies and is formed during DNA replication
  6. 12. cancer-causing substance
  7. 15. structure made of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromosomes before the cell divides
  8. 17. programmed cell death
