All cells, whether they are prokaryotic or eukaryotic, have some common features. The common features of prokaryotic and eukaryotic cells are: 1  DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes.he common features of prokaryotic and eukaryotic cells are: 1  DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes.
Article Summary: There are only two basic types of cells, primitive prokaryotes and the more complex eukaryotes. Here are the main features that distinguish these cell types. Prokaryotes are primarily distinguished by the fact that they lack the eukaryotic feature of a membrane-bound nucleus. In fact, the only membrane in prokaryotic cells is the plasma membrane--the outer boundary of the cell itself.
