C
G1 phase
D
S phase
Verified step by step guidance1
Understand the overall structure of the cell cycle, which consists of interphase (G1, S, and G2 phases) and the mitotic (M) phase.
Recall that during G1 phase, the cell grows and performs normal functions; during S phase, DNA replication occurs; and during G2 phase, the cell prepares for mitosis by producing necessary proteins and organelles.
Recognize that mitosis (M phase) follows the G2 phase, meaning the cell is in G2 immediately before mitosis begins.
Identify that prophase is actually the first stage within mitosis itself, not a phase before mitosis.
Conclude that the correct answer is the G2 phase, as it is the stage right before the cell enters mitosis.
