Webb11 apr. 2024 · All prokaryotic cells have a nucleoid region, DNA, and RNA as their genetic material, ribosomes, and cytosol. Prokaryotic cells use deoxyribonucleic acid (DNA) as the basis for their genetic information. Prokaryotes reproduce with a cell division process called binary fission. Characteristics of Prokaryotic Cell [Click Here for Sample Questions] WebbProkaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 2). Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion, while most pili are used to exchange genetic material during a type of reproduction called conjugation.
