A) They share common features in central apparatus for gene expression and translation.
B) Bacterial gene expression mechanisms differ from those of the eukaryotes, which underlies the selective activity of many antibiotics.
C) Some archaeal cell walls are composed of pseudopeptidoglycan and may have fundamentally different antibiotic sensitivity than bacteria.
