How does DNA replicate? A cell must duplicate, or replicate, all of its DNA before it can divide. In eukaryotes, this process occurs during the S phase of the cell cycle, called the DNA Synthesis phase. During this phase, each chromosone replicates exactly once to form a pair of physically linked sister chromatids. In animal cells, a pair of centrioles is also duplicated during the S phase.
