Understand the cell cycle: The cell cycle consists of several phases that a cell goes through to divide and produce new cells. These phases include G1, S, G2, and M phase.
Identify the S phase: The S phase, or synthesis phase, is where the cell replicates its DNA, ensuring that each daughter cell will have a complete set of chromosomes.
Determine what follows the S phase: After the S phase, the cell enters the G2 phase. This is a period of growth and preparation for mitosis, where the cell checks for DNA damage and begins to form the structures necessary for cell division.
Recognize the role of the G2 phase: During the G2 phase, the cell continues to grow and produce proteins, ensuring that it is ready for the M phase, where mitosis and cytokinesis occur.
Conclude the sequence: The correct sequence of the cell cycle phases is G1 -> S -> G2 -> M. Therefore, the phase that comes immediately after the S phase is the G2 phase.
