Across
  1. 3. Replicated forms of a chromosome joined together by the centromere
  2. 5. division of the cytoplasm to form two separate daughter cells
  3. 9. Series of events that cells go through as they grow and divide
  4. 11. phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin; nuclear membrane begins to reform
  5. 13. process of programmed cell death
  6. 15. In a plant cell, midline of dividing cells. Becomes the cell wall eventually.
  7. 16. A=T and C=G
  8. 18. disorder in which some of the body's cells lose the ability to control growth
  9. 19. Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
  10. 20. Cell organelle that aids in cell division in animal cells only
  11. 22. unwinding, complementary base pairing, and joining
  12. 23. regulatory proteins involved in cell cycle control
Down
  1. 1. part of eukaryotic cell division during which the cell nucleus divides
  2. 2. Protein structures which move the chromosomes during cell division.
  3. 4. Chromosomes become visible, nuclear envelop dissolves, spindle forms
  4. 6. A variable that decreases as cells grow, so that it sets a limit to the size of cells.
  5. 7. new cells produced by cell division
  6. 8. Enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule
  7. 10. Condensed form of DNA present during mitosis
  8. 12. Chromosomes line up in the middle of the cell
  9. 14. Cells grow, performs its normal functions, and prepares for division; consist of G1,S,and G2 phases
  10. 17. An enzyme that unwinds the DNA double helix during DNA replication
  11. 21. relaxed form of DNA in the nucleus of a cell
