Final answer:
DNA replication occurs during interphase's S phase, which is a critical process for the cell to prepare for division by ensuring each daughter cell receives an identical DNA copy.
Step-by-step explanation:
The replication of the DNA occurs during C) interphase, specifically in the S phase (Synthesis phase). During this phase, the cell duplicates its DNA, ensuring that each daughter cell will have an identical set of DNA following cell division. This process is critical for the maintenance of genetic continuity across generations of cells. Interphase is the longest phase of the cell cycle and consists of three stages: G1 phase, S phase, and G2 phase.
During the S phase, DNA replication takes place, resulting in the formation of identical pairs of DNA molecules called sister chromatids. Interphase is the longest part of the cell cycle, where the cell grows, performs its normal functions, and prepares for division. Interphase consists of three phases: G1 (cell growth and protein synthesis), S (DNA replication), and G2 (further growth and preparation for mitosis). DNA replication is a key event in the S phase and is essential before the cell can proceed to mitosis or meiosis.
