State that the most frequently occurring chemical elements in living things are carbon, hydrogen, oxygen and nitrogen. State that a variety of other elements are needed by living organisms, including sulphur, calcium , phosphorus, iron and sodium. State one role for each of the elements mentioned above.
The answer is <span>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.</span>
