So let's actually discuss each one of these individual phases that together make up our interface. So let's begin with the G One phase. So as soon as the cell divides the cell enters the G One phase and the G One phase is known as the growth phase. So basically in this phase our chromosome unwinds and uncoils into Uchromatin and the Uchromatin is used to produce RNA that is used to synthesize the proteins that are needed by the cell and those proteins are used to synthesize the many organelles and the different types of cell machinery that are needed for the cell survival. So the G One phase is the phase where we produce the majority of the organelles and the proteins that are used by the cell. And as a result the cell basically increases in size.
