Mitosis. Light micrograph of a whitefish cell in late anaphase,a stage of mitosis (nuclear division). Mitosis is the formation of two daughter nuclei from one parent nucleus. During anaphase,sister chromatids are moved to separate poles of the cell by microtubules (brown). Chromatids consist of deoxyribonucleic acid (DNA,black). Two identical chromatids make up one chromosome. Microtubules are protein filaments that form spindles,which attach to the chromosomes and pull the sister chromatids to opposite poles of the cell. The cell goes on to divide in half,with each new cell retaining a copy of the parent cell's genetic information | |
