| a. In prokaryotes, transcription and translation take place in  the cytoplasm. | 
    | b. Prokaryotic mRNAs are synthesized with ribosomes  attached. | 
    | c. mRNA splicing occurs very quickly in prokaryotic cells. | 
    | d. Prokaryotic mRNAs are elongated differently from eukaryotic  mRNAs. | 
    
In eukaryotes transcription and translation are separated, mRNA has to be synthesized and transported into the cytosol where all the tranlsation machinary is present. Prokaryotic transcription and translation are not comparmentalized, as a result translation starts by biinding of ribosomes as soon as mRNA is being formed.
