Uncontrolled production of cyclins will most likely result in uncontrolled division of the cell.
CELL DIVISION:
- Cell division is a biological process that every cell undergoes to replicate themselves. It is the process by which cells are multiplied in living organisms.
- According to this question, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. However, at the end of the cycle, the cyclins are degraded to prevent further signaling for the cell to divide.
- In a case whereby there is an uncontrolled production of cyclins, this will most likely result in uncontrolled division of the cell because cyclins stimulate cellular division.
