The events which does not occur during interphase is

Interphase is the longest phase of the cell cycle and consists of three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). During interphase, the cell undergoes growth, carries out its normal functions, and prepares for cell division. However, certain events that are characteristic of other phases of the cell cycle do not occur during interphase. One such event is:

**Mitosis or Meiosis**: Interphase is the phase of the cell cycle that precedes mitosis (in somatic cells) or meiosis (in germ cells). Mitosis and meiosis occur after interphase, during the mitotic (M) phase of the cell cycle. During mitosis or meiosis, the cell undergoes nuclear division, leading to the formation of daughter nuclei.

Therefore, the event that does not occur during interphase is mitosis or meiosis.
