What occurs during the S-phase of the cell cycle?

[RamonitaBe]

I'm studying the stages of the cell cycle and want to know what happens in the S-phase. Can someone explain its main function and importance?

During the S-phase (Synthesis phase) of the cell cycle, the cell replicates its DNA, creating an identical copy of each chromosome. This ensures that when the cell later divides during mitosis or meiosis, each daughter cell receives a complete set of genetic information.

A cell is used to generate its DNA in the S-phase (Synthesis phase) such that each chromosome is replicated. This is such that new cells that have arisen after division inherit the same genetic material.

During the S-phase (synthesis phase) of the cell cycle, the cell replicates its DNA, ensuring each chromosome is copied to form two identical sister chromatids. This process doubles the cell’s genetic material, preparing it for division. Key enzymes like DNA polymerase help ensure accurate replication, maintaining genetic stability for the next cell generation.
