During the cell cycle, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. At the end of this cycle, the cyclins degrade to prevent further signaling for the cell to divide.

Uncontrolled production of cyclins will most likely result in-

  1. the formation of cancer cells
  2. healthy cells
  3. the transfer of cyclins
  4. an increase in mitochondria within the cell
  • the formation of cancer cells
