A) In bacteria, but not eukaryotes, RNA polymerase binds the promoter directly.
B) Bacteria, but not eukaryotes, have non-coding regions called introns in their genes, which must be removed from mRNA following transcription.
C) In bacteria, but not eukaryotes, translation can begin on a particular mRNA, before transcription of that same mRNA molecule is complete.
D) The ribosomes used by bacteria in translation are smaller and somewhat different in structure than those used by eukaryotes.
E) Gene expression is generally quicker in bacteria than it is in eukaryotes.
