In this lecture we're going to discuss the process of the interface or the stage known as interface. Now interface is the stage of the life cycle of the animal cell that prepares the cell for the process of cell division. Interface is the longest stage of the life cycle of that cell and it takes up about 90% of the time. Now the reason it's so long is because interphase actually consists of three individual phases. We have the G One phase, the S phase as well as the G Two phase. Now each one of these phases basically serves its own unique function.
