Which phase is the longest phase in the cell cycle in eukaryotic cells?

The cell cycle is divided into two stages: interphase and M phase. The longest phase in the cell cycle in eukaryotic cells is interphase, which is divided into three subphases: G1, S, and G2. During G1, the cell grows and carries out normal functions. In the S phase, DNA replication occurs. In G2, the cell checks for DNA damage and makes sure all is correct before proceeding to mitosis. Interphase is the stage of the cell cycle in which the cell grows and replicates its DNA in preparation for cell division.
