"Growth of cell and replication of DNA."
Interphase (G1, S, G2) is the active preparatory stage: G1 — cell growth and organelle production; S — DNA replication; G2 — further growth and synthesis of proteins/checkpoints to ensure DNA is intact and mitotic machinery is ready. It is not a resting phase, does not dissolve the nucleus or cell membrane (that happens in prophase/prometaphase), and does not divide the cytoplasm (cytokinesis occurs after mitosis).
