In a Nutshell
Your body is made up of TRILLIONS of cells that all have different responsibilities. That is a LOT of cells!!
In order for your body to function correctly, these cells need to work in unison by communicating with each other.
Your cells also go through a process called the cell cycle in order to generate new cells.
Before we begin…
A good way to remember the importance of regulation in cell communication and the cell cycle is to think of a checklist. In order for these processes to be done correctly, there must be correct timing and coordination within the cell.
