interphase; mitosis

Explanation:

1. Cytokinesis is the process of the cell - cytoplasm dividing to form two separate cells. Mitosis only divides the nucleus. So, cytokinesis is needed to form two cells.
2. During interphase, the cell grows, performs normal functions and replicates its DNA. Mitosis is the process where the nucleus divides and chromosomes separate into two nuclei.

Answer:
