Now, mitosis can be broken down into ProPhase, metaphase, anaphase and telephase. And the process by which the cell actually divides is known as cytokinesis. And we'll discuss that in the next lecture. So basically the process of interface is the first stage of the life cycle of an animal cell. Interface consists of the G one phase, the S phase and the G two phase. In the G one phase the cell basically grows in size because the majority of the proteins and organelles are synthesized within our cell.
