During which phase is DNA synthesized in a eukaryotic cell?

• A. M Phase
• B. S Phase
• C. G1 Phase
• D. G2 Phase

Answer: (B)

DNA is synthesized during the S Phase of the cell cycle, which stands for "synthesis." During this phase, the entire genome of a eukaryotic cell is replicated, allowing for the creation of identical sister chromatids in preparation for cell division. This process is crucial, as it ensures that each daughter cell will receive an identical set of chromosomes after the cell divides. The S Phase is sandwiched between the G1 Phase, where the cell grows and produces the necessary proteins and organelles, and the G2 Phase, where the cell continues to grow and prepares for mitosis. The M Phase refers to mitosis itself, where the actual division of the cell occurs, and does not involve DNA synthesis.
