In the S phase, the DNA of the chromosomes is replicated. Finally, in the G2 phase, the cell undergoes the final preparations for meiosis.
What phase do most cells spend the majority of their life in? The cell spends most of its like in the interphase. This is because the interphase is the phase where the cell grows and it is also when the cell preps for the mitotic/meiotic process. In the interphase process the cell goes through G1, S, and G2 phase which takes a majority of the cells life.
