B) there is only one type of RNA polymerase.
C) transcript mRNAs are polycistronic.
D) transcript mRNAs undergo processing after translation.
E) All of the answers are differences.

In prokaryotes, translation can begin while mRNA is still being transcribed due to the lack of a nuclear membrane, there is indeed only one type of RNA polymerase handling all transcription, and their mRNAs can be polycistronic, meaning they can encode multiple proteins within the same mRNA molecule. In contrast, eukaryotic mRNAs are typically monocistronic and undergo extensive processing (such as capping, polyadenylation, and splicing) before translation, which does not occur in prokaryotes as described in option D.
