Which phase of the cell cycle consists of G1, S, and G2 and involves growth and preparation for division?

Explanation:
Interphase is the phase where the cell grows and readies itself for division, encompassing three sub-stages: G1, S, and G2. In G1, the cell increases in size and carries out normal metabolic activities. During S, DNA is replicated so each new daughter cell will inherit a complete genome. In G2, the cell grows further and produces the proteins and structures needed for mitosis, while also checking for any DNA errors before division. This phase is the longest part of the cell cycle, setting the stage for the actual division that occurs in the subsequent mitotic stages.
