Mitosis in binucleate cells, light micrograph

---

Differential interference contrast (DIC) light micrograph of an onion (Allium cepa) meristematic cell with two nuclei in the anaphase stage of mitosis (nuclear division). Mitosis is the formation of two daughter nuclei from one parent nucleus. At anaphase, sister chromatids (red) are separated to opposite ends of the cell. Two identical chromatids make up one chromosome, so each cell retains a copy of the parent cell's genetic information. Orcein staining.
