where is the dna located in a prokaryote cell?
nucleus
bacteria do not have a membrane-bound nucleus, and their genetic material is typically a single circular bacterial chromosome of dna located in the cytoplasm in an irregularly shaped body called the nucleoid. the nucleoid contains the chromosome with its associated proteins and rna. like all other organisms, bacteria contain ribosomes for the production of proteins, but the structure of the bacterial ribosome is different from that of eukaryotes and archaea.
bacteria
the eukaryotic cell seems to have evolved from a symbiotic community of prokaryotic cells. dna-bearing organelles like mitochondria and chloroplasts are remnants of ancient symbiotic oxygen-breathing bacteria and cyanobacteria, respectively, where at least part of the rest of the cell may have been derived from an ancestral archaean prokaryote cell. this concept is often termed the endosymbiotic theory. there is still debate about whether organelles like the hydrogenosome predated the origin of mitochondria, or "vice versa": see the hydrogen hypothesis for the origin of eukaryotic cells.
