cell duplicates its DNA
During S phase :)
DNA replication happens during s-phase.
Cells increase in Mass during G [growth] Phase and DNA replication occurs during S [synthesis] Phase.
After the S phase in the cell cycle, cells enter the G2 phase where they continue to grow and prepare for cell division. During the G2 phase, the cell undergoes further growth and replicates important organelles. Finally, the cell enters the M phase (mitosis) where it divides into two daughter cells.
During the G2 phase of the cell cycle, the cell continues to grow and prepare for DNA replication. It is a checkpoint phase where the cell checks for any damage or errors before moving on to the next phase of the cycle. If conditions are favorable and the cell is healthy, it will proceed to the S phase for DNA replication.

cell duplicates its DNA
Cells undergo a round of DNA replication during the S phase of the cell cycle. This is when the cell duplicates its DNA to prepare for cell division.
During the S phase, new DNA is synthesized when the chromosomes are replicated, The cell at the end of the S phase contains twice as much DNA as it did in the beginning.
When cells are forming, they are typically in the M phase (mitosis) or G1 phase (the first gap phase after mitosis). The phase that is not operating during this process is the S phase (synthesis phase), where DNA replication occurs. Therefore, if cells are actively dividing and forming new cells, the S phase is not in operation at that moment, as they are either completing division or preparing for the next cycle.
synthesis of DNA DNA Replication
The DNA replicates before mitoses begins DNA replication occurs in the S phase of interphase (before mitosis)
