Solution

The correct option is C mRNA codons
One way of detecting a specific cloned gene is by detecting its protein product expressed in the bacterial cell. In these cases, it is necessary to be able to express the gene in bacteria, that is, to transcribe it and translate the mRNA into protein. If a eukaryotic gene is incorrectly inserted into a plasmid vector the recipient bacterium may fail to express the gene because it cannot recognize the eukaryotic mRNA codons.
Thus, the correct answer is option C.
