What is the stage of interphase during which the DNA is replicated?

G1 phase
G2 phase
S phase
Prophase

The correct answer is: G1 phase

The stage during which DNA is replicated is called the S phase. This is because during this phase, the cell's DNA is synthesized or copied, creating two identical sets of genetic material. Therefore, options B, C, and D are incorrect as they refer to other stages of the cell cycle that do not involve DNA replication. G1 phase is the first stage of interphase where the cell grows and prepares for DNA replication, G2 phase is the last stage of interphase where the cell continues to grow and prepares for mitosis, and prophase is the first stage of mitosis where the cell's genetic material condenses and prepares for cell division. Therefore, A is the correct answer as it specifically refers to the phase where DNA replication occurs.
