Cell division. Cytokinesis occurs after nuclear division (mitosis), which produces two daughter nuclei (blue and pink) from one parent nuclei. Here the nuclear envelopes (red) are reforming around the chromatin (blue), the complex of DNA (deoxyribonucleic acid) and protein that forms chromosomes. Microtubules, which moved the DNA to the new nuclei, are yellow.
