... Under a microscope, archaea look very similar to bacteria. Both are equally small, lack nuclei, and have cell walls, but there are important differences. The walls of archaea lack peptidoglycan, and their membranes contain different lipids. The DNA sequences of key archaea genes are more like those ...
