Mitosis

The stages of Mitosis are as follows:
  • 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.
