Which one of the following statement is NOT correct regarding the cell-cycle control switch system?

#Unit 2. Cellular Organization
  1. The switches are generally binary (on/off) and launch events in a complete, reversible fashion.
  2. The system is robust and reliable, allowing the system to operate effectively under a variety of conditions and even if some components fail.
  3. The control system is highly adaptable. 
  4. The control system can be modified to suit specific cell types or to respond to specific intracellular or extracellular signals.
