C
Chromosome segregation
D
Cytokinesis
Verified step by step guidance
1
Understand the cell cycle: The cell cycle consists of interphase and the mitotic phase. Interphase is the period of growth and preparation for cell division.
Identify the stages of interphase: Interphase is divided into three stages: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
Focus on the S phase: During the S phase of interphase, DNA replication occurs. This is when the cell duplicates its DNA, ensuring that each daughter cell will have a complete set of chromosomes.
Differentiate from other processes: Nuclear envelope breakdown, chromosome segregation, and cytokinesis occur during the mitotic phase, not interphase.
Conclude with the correct process: Therefore, the process that occurs during interphase is DNA replication, specifically during the S phase.
