Protein synthesis
Verified step by step guidance

Understand the phases of the cell cycle: The cell cycle consists of interphase and the mitotic phase. Interphase is further divided into G1, S, and G2 phases.
Identify the activities during interphase: During interphase, the cell undergoes growth (G1 phase), DNA replication (S phase), and preparation for mitosis (G2 phase). Protein synthesis occurs throughout interphase to support these activities.
Clarify the role of mitosis: Mitosis is the process of cell division where the nucleus divides, resulting in two daughter cells. It is not part of interphase but occurs after interphase during the mitotic phase.
Recognize the distinction: Since mitosis is the division of the cell's nucleus, it does not occur during interphase. Interphase is dedicated to preparing the cell for mitosis through growth, DNA replication, and protein synthesis.
Conclude the answer: Based on the understanding of the cell cycle, the process that never occurs during interphase is mitosis, as it is part of the mitotic phase.
