What Phase in the cell cycle from cell formation until the start of cell division?

The phase in the cell cycle from cell formation until the start of cell division is known as interphase. Interphase is divided into three sub-phases: G1 (gap 1), S (synthesis), and G2 (gap 2). During this time, the cell grows, duplicates its DNA, and prepares for mitosis. Interphase is crucial for ensuring that the cell is ready for the subsequent division phase.
