Across
  1. 5. subunit (monomer) of nucleic acid formed from a simple sugar, a phosphate group and a nitrogen base
  2. 8. structure that joins two sister chromatids
  3. 11. main stage of the cell cycle during which the cell's replicated DNA divides and 2 genetically identical diploid daughter cells are produced
  4. 12. stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided.
  5. 14. form of DNA in the nucleus of a cell
  6. 17. stage of mitosis in which sister chromatids are pulled apart and moved to opposite poles of the cell
  7. 19. of the specific proteins that regulate the cell cycle
  8. 21. stage of mitosis, during which the cell's chromatin condenses into chromosomes
  9. 22. structure that carries genetic material from one generation to another
  10. 23. stage of the cell cycle, during which a cell grows, matures and replicates DNA
Down
  1. 1. central membrane-bound organelle that manages cellular functions and contains DNA
  2. 2. growth and division in cells that can be caused by changes in control of the cell cycle and/or environmental changes
  3. 3. small region located near the nucleus in the cytoplasm, containing the centrioles
  4. 4. unit of structure and organization of all living things
  5. 6. subunit of chromatin fibers, consisting of DNA coiled around histones
  6. 7. cancer-causing substance
  7. 9. kinase-enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle
  8. 10. main stage of the cell cycle, during which the cell's cytoplasm divides, creating a new cell
  9. 13. cells-either of the two genetically identical cell that form when a cell divides
  10. 15. hereditary molecule inside cells that contains the genetic coding responsible for the development and function of an organism
  11. 16. Cycle-process of cellular reproduction, occurring in 3 main stages - interphase (growth), mitosis (nuclear division), and cytokinesis (cytoplasm division)
  12. 18. programmed cell death
  13. 20. apparatus-structure made of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromosomes before the cell divides
