WebbPhylogeny of prokaryotes inferred by rRNAs or genes has been immensely successful. However, there are some problems in this kind of methods. The phylogenetic trees inferred from single rRNAs or genes may have many conflicts because of the various biological phenomena [ 5 ], such as horizontal gene transfer (HGT) [ 6 – 8 ], hybridization, lineage … WebbThree-domain system.

"WebbThey are called prokaryotes. Virtually all the life we see each day — including plants and animals — belongs to the third domain, Eukaryota. Eukaryotic cells are more complex than prokaryotes, and the DNA is linear and found within a nucleus. Eukaryotic cells boast their own personal “power plants”, called mitochondria.
