Which phase of the cell cycle is characterized by DNA replication?

Explanation:
DNA replication happens in the synthesis phase, the part of interphase when the genome is duplicated to produce two identical copies for sister chromatids. During this phase, DNA is copied by polymerases, creating semi-conservative replication with leading and lagging strands proceeding from origins of replication. G1 is prior growth and preparation without DNA duplication, G0 is a non-dividing state, and interphase is the overall period that includes G1, S, and G2; however, the actual duplication of the genome occurs specifically in the synthesis phase.
