Verified step by step guidance

Understand the cell cycle phases: The cell cycle consists of several phases, including G1, S, G2, and M. Each phase has distinct characteristics and functions.

Identify the DNA replication phase: During the S phase (Synthesis phase), DNA replication occurs, doubling the amount of DNA in the cell.

Consider the G2 phase: After the S phase, the cell enters the G2 phase, where it prepares for mitosis. At this point, the cell contains the most DNA because it has completed DNA replication.

Compare DNA content in each phase: In G1, the cell has a normal amount of DNA. In S, DNA is being replicated. In G2, the cell has double the DNA compared to G1. G0 is a resting phase with normal DNA content.

Conclude that the G2 phase has the most DNA: Since DNA replication is complete by the end of the S phase, the G2 phase is when the cell contains the most DNA per cell.
