Question

During which phase of the cell cycle is a cell's DNA copied?

Answer 1

During the S phase (Synthesis Phase)

Step-by-step explanation:

S phase happens during Mitosis; the formation of two daughter cells by using synthesis.

Answer 2

The answer to this question will be "Mitosis." During Mitosis the DNA cell is replicated during the cell cell cycle. Mitosis is basically cell division that equals two copied daughter cells with the same amount of chromosomes as each other during the cell cycle.

Hope this helps.
