Frederick Roy · Answer 1

The answer is Special RNA polymerase, peptidoglycan in cell walls, ester-linked fatty acids.

Bacterial cell wall consists of peptidoglycans, not of cellulose or chitin. They also have ester-linked fatty acids, like eukaryotes. Ether-linked fatty acids are characteristics of Archaea. Also, bacteria have special RNA polymerase, unlike Eukaryotes that have three different type of RNA polymerase.
