During which phase does the cell primarily grow and metabolize, preparing for DNA replication?

• A. G1 phase
• B. S phase
• C. G2 phase
• D. Mitosis

Answer: (A)

The phase focused on growth and metabolic activity before copying the genome is the first gap phase. In this stage, the cell increases in size, ramps up protein and organelle production, and carries out normal metabolic functions to stockpile energy and materials needed for DNA synthesis. Once these resources are built, the cell proceeds to the next phase where DNA replication occurs. The following phase continues growth but centers on preparing for mitosis, and mitosis is the actual division.
