The phase of the cell cycle that involves the replication of DNA is the S Phase, which stands for "Synthesis Phase." During this phase, each chromosome in the nucleus is replicated, resulting in the formation of sister chromatids. This DNA synthesis is crucial as it ensures that, when the cell divides, each daughter cell will receive an identical set of chromosomes, maintaining genetic consistency across generations of cells. The S Phase is essential for cell division, as it prepares the cell by doubling its genetic material in advance of mitosis.

In contrast, the M Phase refers to mitosis, where the actual separation of chromosomes into two daughter cells takes place, but no DNA replication occurs. The G2 Phase is a preparatory stage after DNA synthesis, where the cell checks for any errors in the replicated DNA and prepares for mitosis. Cytokinesis, on the other hand, is the process that follows mitosis and involves the division of the cytoplasm, ultimately resulting in the creation of two distinct, fully-formed cells, but it does not involve any DNA replication.
