Answer:
Option (A), (B), (D) and (F).
Explanation:
Bacteria are involved in the domains of eubacteria and archaea. Bacteria are different from the other organism and shows different in the chemical and cellular structure of the cell.
The translation elongation factors are different in bacteria and other organisms. The translation factors of bacteria are EF-Tu and EF-Ts whereas the eukaryotic elongation factors are eEF-1 subunit α and eEF-1 subunit βγ. A single RNA pol is present in bacteria and three different RNA pol is present in eukaryotes. Peptidoglycan is present in prokaryotes. Phospholipids contain ester linkage in bacteria and ether linkage in archaea.
Thus, the correct answer is option (A), (B), (D) and (F).
