Answer:
Polycistronic mRNAs
Explanation:
Normally In Eukaryotic cells the messenger RNAs (mRNA) only contain the information to produce a protein, these mRNAs are known as monocistronic.
In Prokaryotes, the transcription system is usually polycistronic, this means that a mRNA have the information to encode two or more genes.
As an interesting example of the co-evolution of Eukaryotes, the mitochondrial genome has polycistronic genes.
