The terms prokaryote and eukaryote refer to the differences in the location of the DNA. In prokaryotes the DNA is not enclosed by nuclear membranes and lies free in the cytoplasm. The cells therefore lack true nuclei . The cells of eukaryotes, however, do contain true nuclei. Eukaryotes arose around 1.2 thousand million years ago, and they evolved from prokaryotes which began around 3.5 thousand million years ago. Although the location of the DNA in the cells is the major difference between the cell types, there are many more differences, which are explored below. The sizes of the cells are vastly different, in prokaryotes the average diameter of the cell is 0.5-10µm. However, eukaryote cells are much larger in comparison, they are typically...
