The correct sequence of cell cycle is ïƒ G1 -> S -> G2 -> M
The cell cycle is the process by which a cell increases in size in preparation for cell division. In this process. The cell copies its DNA, synthesizes and prepares for division, and then it divides.
Gap 1 (G1) Stages is when the DNA is copied. The synthesis (S) phase is the phase in which the copied DNA is replicated. It occurs between G1 and G2. At Gap 2 (G2) phase, the DNA has replicated, and the cell is getting set for division, more molecules are produced to enable the process of cell division. Finally, the cell goes into Mitosis (M) phase.
G1, S, and G2 make up interphase. The M phases are divided into 4 phases: prophase, metaphase, anaphase, and telophase.
