Full Answer

There are several stages involved in the cell cycle: the G1 phase, S phase and the G2 phase. The G1 phase prepares the cell to undergo the next stage of synthesis. The S phase is where all chromosomes are duplicated and the DNA is replicated. During the G2 phase, the cell prepares itself for mitosis by synthesizing all of the needed components. After this follows the interphase, prophase, metaphase, anaphase and telophase.
