    Q:

    		 To properly express human proteins in prokaryotic systems, human mRNAs typically must first be reverse transcribed to DNA before being transformed into the prokaryote for expression. Reverse transcription of the mRNA to DNA is necessary for proper expression because
    		 

    A

    		 prokaryotes do not use the same set of nucleotides as humans and need to be transformed with human DNA.

    B

    		 prokaryotes are unable to perform the correct post-translational modifications on the human proteins.

    C

    		 prokaryotes are unable to splice exons and the human mRNA has the exons spliced.

    D

    		 prokaryotes are unable to translate human genes.
