During which specific phase of interphase is DNA replicated?

Explanation:
DNA replication happens during the S phase of interphase. During this phase, the cell duplicates its entire genome, producing sister chromatids for each chromosome that stay connected at the centromere until mitosis. This doubling of DNA content ensures that, when the cell eventually divides, each daughter cell receives an identical set of chromosomes. The other interphase phases are for growth and preparation (G1 and G2), while mitosis (M phase) is when chromosomes are separated, not replicated.
