Detailed explanation-1: -There are three stages in the interphase, the cell grows in the G1 phase, DNA synthesis takes place in S phase and synthesis of proteins and growth continues in G2. At the end of the interphase, the cell is fully prepared for the division and enters the M phase of the cell cycle.

Detailed explanation-2: -G2 phase is a period of rapid cell growth and protein synthesis during which the cell prepares itself for mitosis. Curiously, G2 phase is not a necessary part of the cell cycle, as some cell types (particularly young Xenopus embryos and some cancers) proceed directly from DNA replication to mitosis.

Detailed explanation-3: -So, what happens in G2 of the cell cycle? The second growth phase starts to prepare the cells with newly replicated DNA for entry into the mitosis phase by putting in place the necessary organelles for mitosis.

Detailed explanation-4: -G2 is the shortest phase of interphase. It is when organelles and proteins necessary for cell division are produced. The cell requires a bunch of proteins and other stuff to separate the chromosomes and divide the cell in half. All of these materials are produced during G2.

Detailed explanation-5: -G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA. So, S stands for DNA synthesis.
