Prokaryotes and Eukaryotes 2 Prokaryotes are single-celled organisms, such as bacteria, and are roughly one micrometer in diameter. Unlike Eukaryotes, prokaryotes do not have a nucleus that houses its genetic material. Rather, the genetic material of a prokaryote cell consists of a large DNA molecule compacted in an area of cytoplasm called the nuclei region. The nuclei region is protected and encased by the cell wall, or cell membrane, the outer layering of the cell. Finally, a flagellum, a rudder-like device, affords the prokaryote the luxury of mobility. One differentiating characteristic is that prokaryotes are asexual, meaning their offspring nearly always bear the exact characteristics of the parent cell. Since the Prokaryotes exhibit this asexual behavior as opposed to sexual behavior, where a recombination of chromosomes occurs to form unique entities, evolution of the prokaryotic cell has been fairly stagnant over its two
