Prokaryotes possess linear chromosomes bound to histone proteins inside a nuclear membrane, whereas eukaryotes have circular naked DNA. Prokaryotes store genetic material as a single circular chromosome in the nucleoid region and often contain small accessory plasmids, whereas eukaryotes have multiple linear chromosomes wrapped around histones in a membrane-bound nucleus. Prokaryotic DNA contains introns that must be spliced out before translation, whereas eukaryotic DNA consists entirely of continuous protein-coding exons. Prokaryotic chromosomes undergo mitosis during cell division, whereas eukaryotic chromosomes undergo binary fission.
