Mitotic spindle, made of microtubules, forms. One chromatid of each chromosome gets pulled to each pole of the cell. A nuclear membrane forms around each set of chromosomes, resulting in two daughter nuclei. The cell plate forms. DNA interacts with histones to form nucleosomes.
Prokaryotes typically have a single chromosome.
Prokaryotes typically divide by meiosis. I consists of two chromatids. I spontaneous mutations in skin cells spontaneous mutation in sperm or egg DNA 43. Chromosomes contain both DNA and proteins. Eukaryote chromosomes sometimes consist of two chromatids.
