# The Stages of Mitosis The stages of mitosis are described below: **Stage 1:** Before mitosis, chromosomes are long, thin structures located in the nucleus of a cell. They are visible under a microscope. Before mitosis can begin, each chromosome replicates to produce two identical sister chromatids, joined at the centromere. At the start of mitosis, chromosomes condense and become more visible, and the nuclear membrane begins to break down. **Stage 2:** Chromosomes line up along the cell's equator. Spindle fibers from each pole of the cell attach to each of the chromatids at specific centromere regions. **Stage 3:** Spindle fibers pull the chromatids apart towards opposite ends of the cell. **Stage 4:** The nuclear membranes reform, and the cytoplasm divides. **Stage 5:** Two daughter cells are produced. Each daughter cell contains a complete set of chromosomes identical to those of the parent cell. These cells are diploid, meaning they contain the same number of chromosomes as the original cell. **Stage 6:** Two daughter cells are formed, each with the identical genetic information of the parent cell. They are diploid cells. **Diagram:** The document contains diagrams illustrating each of the stages described above. Unfortunately, the diagrams are not standardized but help visualize the changes in chromosome structure during the mitotic process.
