what happens in s phase of interphase

In the S phase of interphase, DNA synthesis occurs, leading to the replication of the genetic material. This phase is crucial for the cell cycle as it ensures that each daughter cell receives an identical copy of the genetic material. Additionally, the centrosomes, which are responsible for organizing the mitotic spindle, are also replicated during the S phase/10%3A_Cell_Reproduction/10.02%3A_The_Cell_Cycle/10.2A%3A_Interphase). This phase is a fundamental part of the cell cycle, ensuring the accurate transmission of genetic information to the next generation of cells.
