S phase
Wikipedia.org
The S phase, short for synthesis phase, is a period in the cell cycle during interphase, between G1 phase and the G2 phase. Following G1, the cell enters the S stage, when READ MORE http://en.wikipedia.org/wiki/S_phase
G1 Phase

The G1 phase is a period in the cell cycle during interphase, before the S phase. For many cells, this phase is the major period of cell growth during its lifespan.

G2 phase is the third, final, and usually the shortest subphase during interphase within the cell cycle in which the cell undergoes a period of rapid growth to prepare for READ MORE http://en.wikipedia.org/wiki/G2_phase
Interphase

In interphase, the cell gets itself ready for mitosis or meiosis. Somatic cells, or normal diploid cells of the body, go through mitosis in order to reproduce themselves READ MORE http://en.wikipedia.org/wiki/Interphase
Before a cell begins to divide, it goes through an interphase where it replicates its genetic information and all of the organelles. Interphase has three stages, G1, S, and G2.
