DNA replication
D
Chromosome segregation
Verified step by step guidance
1
Understand that interphase is a phase of the cell cycle where the cell prepares for division. It is not a part of mitosis but is crucial for cell division.
Recognize that interphase consists of three stages: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
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.
Cytokinesis is the process of cytoplasmic division and occurs after mitosis, not during interphase.
Nuclear envelope breakdown and chromosome segregation are events that occur during mitosis, not interphase. Therefore, DNA replication is the correct event that occurs during interphase.
