In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes ...
Note that eukaryotic cells likely evolved from a symbiotic relationship between two prokaryotic cells, whereby one set of prokaryotic DNA eventually became separated by a nuclear envelope and ...
Eukaryotic cell DNA in a nucleus, plasmids are found in a few simple eukaryotic organisms. Prokaryotic cell DNA is a single molecule, found free in the cytoplasm; additional DNA is found on one or ...
