Interphase

Interphase is actually the longest phase of the cell cycle. It is divided up into three phases: The G1 Phase, the S Phase, and the G2 Phase. In the G1 Phase, the cell does most of its growing. It increases in size and synthesizes new proteins and organelles. In the S Phase, chromosomes are replicated and the synthesis of DNA molecules takes place. Once the replication of DNA is completed, the cell enters the G2 Phase, the shortest of the three phases of Interphase. During this phase, many of the organelles and molecules required for cell division are produced, preparing the cell for the M Phase.

Now, you can move onto the M Phase or return to the Main Page.
