Which phase does the cell primarily increase cytoplasmic volume and prepare for DNA synthesis?

• A. S phase
• B. G1
• C. G0
• D. Interphase

Answer: (B)

Growth and preparation for the next steps happen during the first gap phase after mitosis. In this phase, the cell increases cytoplasmic volume, grows size, and ramps up production of proteins and organelles needed for DNA replication. It also checks that resources and conditions are suitable before entering DNA synthesis. DNA replication occurs in the following phase, so that phase focuses on copying the genetic material rather than expanding the cytoplasm. A non-dividing state describes another phase where the cell isn’t actively preparing to divide, and the term for the entire stretch of growth, DNA synthesis, and preparation periods is interphase, not a single phase. Therefore, the phase that primarily increases cytoplasmic volume and prepares for DNA synthesis is G1.
