Interphase. This is the phase where the cell prepares for the next round of division. It has three phases further, Gap1, synthesis, and gap 2. During Gap1, the cell acquired nutrients and increases in size. The checkpoints ensure that the cell is normal and all the things necessary for DNA synthesis are prepared. During synthesis phase, DNA replicates. During the Gap 2 phase, the cell grow further and the checkpoints ensure that the cell is correctly prepared for mitosis phase. The cell spends most of its time in G1 phase, followed by S phase. Remaining phases comprise only very short period of the cell cycle. Solution Interphase.
