Detailed explanation-1: -During the second gap phase, or G 2start subscript, 2, end subscript phase, the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis.
Detailed explanation-2: -The G0 phase is a form of the resting state, or quiescence, in which cells reside until they receive appropriate signals-for example, from growth factors-stimulating them to re-enter and progress through the cell cycle.
Detailed explanation-3: -Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents.
Detailed explanation-4: -The first phase of cell division is prophase. Hence, prophase occurs after the G2 phase.
