Answer:
Growth of cell and replication of DNA.
Explanation:
The cell cycle has three stages, the interphase, mitosis, and the G0 phase.
Interphase is before mitosis, and it prepares the cell for its division. Interphase has three phases: 
- G1, where the cell grows in size due to the growth of organelles and components, which the cell will need later. 
- In the S phase, the cell synthesizes a copy of the DNA.
-  The G2, where the cell keeps growing and producing organelles and other elements that will need for mitosis.
In conclusion, in the interphase, the cell grows and replicates its DNA.
