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 separated from the rest of the cell by a nuclear membrane (also called a nuclear envelope).Eukaryotic cells also contain a variety of structures and organelles not present in prokaryotic cells.ver time, portions of the DNA from the other prokaryote remaining in the cytoplasmic part of the cell may or may not have been incoporated into the new eukaryotic nucleus (Figure 3). Figure 3: Origin of a eukaryotic cell. A prokaryotic host cell incorporates another prokaryotic cell.
