Across
  1. 4. this is true of the new cells at the end of Mitosis compared to the parent cell
  2. 5. the protein that increases in amount during certain phases of the cell cycle until it reaches a threshold; allowing it to bind to CDK
  3. 7. the checkpoint where proper cell growth will be checked
  4. 9. programmed cell death that occurs if a cell is unfit to progress through the cell cycle
  5. 11. the stage of the cell cycle that involves equally dividing chromosomes and pushing them to opposite sides of the cell
  6. 12. the enzyme involved in initiating progression through the cell cycle
  7. 13. the stage of the cell cycle that involves the final cytoplasmic division into two new daughter cells
  8. 14. genes that code for proteins that progress the cell cycle
  9. 16. genes that code for proteins that stop the cell cycle
Down
  1. 1. a feedback mechanism that involves producing a response until a set point is reached and then decreasing the response
  2. 2. the stage of interphase when DNA is replicated
  3. 3. the stage of the cell cycle where a cell is suspended and will either fail to divide completely (as with cardiac muscle cells) or will only divide when a signal is received (as with platelets)
  4. 4. the portion of the cell cycle where a cell spends most of its time completing normal cell functions and preparing to divide
  5. 6. if these occur to any protein involved in cell cycle regulation or cell signalling, undesired results may occur
  6. 8. the checkpoint where proper DNA replication will be checked
  7. 10. signals that must be received by cells in G0/G1 if they are to proceed through the rest of the cell cycle
  8. 12. the result that occurs if cells progress unregulated through the cell cycle
  9. 15. the letters that represent the order of the phases of Mitosis
  10. 17. the gene and protein involved in halting a cell while DNA repairs, initiates repair enzymes, and initiates apoptosis if repair is not successful
