In the domain system of classification, prokaryotes are divided into two domains: bacteria and archaea. the two domains differ in all but one feature. that is, both

That is, both have prokaryotic cells

The two prokaryotic domains differ greatly but all organisms in these domains have prokaryotic cells. Members of the domain Archaea live in extreme environments, including anaerobic conditions. Also, the Archaea have cell walls that are different from the Bacteria as their walls do not contain peptidoglycan. Some scientists believe the Archaea to be more closely related to the eukaryote.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
