Detailed explanation-1: -G1 is followed by S phase (synthesis), during which DNA replication takes place. The completion of DNA synthesis is followed by the G2 phase (gap 2), during which cell growth continues and proteins are synthesized in preparation for mitosis.

Detailed explanation-2: -Chromosome Dynamics During the Cell Cycle. The G1, S, and G2 phases are often referred to as interphase, and the M phase is the mitotic phase. During interphase, chromosomes are replicated, and during mitosis they become highly condensed and then are separated and distributed to the two daughter nuclei.

Detailed explanation-3: -S phase (DNA Synthesis)-Each of the 46 chromosomes are duplicated by the cell.

Detailed explanation-4: -Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth).

Detailed explanation-5: -During the G2 phase of the cell cycle the cell produces additional organelles and proteins necessary for cell division. The cell cycle starts with G1 phase, where cells are growing larger and doing their job in the body.
