What is compromised of G1 S and G2 phase?

The cell cycle consists of several phases, with G1, S, and G2 phases being key components of interphase. G1 (Gap 1) is the phase where the cell grows and prepares for DNA replication, while the S (Synthesis) phase is when DNA is replicated, resulting in two complete sets of chromosomes. Following S phase, G2 (Gap 2) is a further growth phase where the cell prepares for mitosis, ensuring all necessary components for cell division are ready. Together, these phases ensure proper cell growth, DNA integrity, and readiness for division.
