Whats the difference between Bacteria and Archaea?

Archaea differ from bacteria in that they have histone proteins associated with their DNA as we do. Like us, they have no muramic acid in their cell walls and they use methionine as their initiator tRNA whereas bacteria use Formylmethionine. Also like us, their ribosomes are sensitive to diphtheria toxin, those in bacteria are not. They are insensitive to chloramphenicol, streptomycin and kanamycin, whereas most bacteria are sensitive to these substances. Like bacteria, some of them are capable of denitrification and nitrogen fixation but unlike bacteria none of them are capable of nitrification. Also like bacteria some of them are capable of growth at temperatures above 80°C. No eukaryotes (us, plants, etc.) are capable of this. They differ from both eukaryotes and bacteria in that their membrane lipids are ether-linked not ester-linked and in that they are capable of methanogenesis.”
