DNA, Protein Synthesis, Cell Cycle

At what point in the cell cycle does DNA replication occur and why?

• before a cell divides, to provide each of the two resulting cells with a complete set of DNA instructions
• before a cell divides, to ensure that the DNA will fit into the resulting cells
• during cell division, to ensure that the DNA will fit into the resulting cells
• after a cell divides, to provide each of the two resulting cells with a complete set of DNA instructions
