- Interphase- The cell grows and replicates its DNA and centrioles.
- Prohase- The chromatin condenses into chromosomes. The centrioles separate, and a spindle begins to form. The nuclear envelope breaks down.
- Metaphase- The chromosomes line up across the center of the cell. Each chromosome is connected to a spindle fiber at its centromere.
- Anaphase- The sister chromatids separate into individual chromosomes and are moved apart.
- Telophase- The chromosomes gather at opposite ends of the cell and lose their distinct shapes. Two new nuclear envelopes will form.
- Cytokinesis- The cytoplasm pinches in half. Each daughter cell has an identical set of duplicate chromosomes.
