Can one mRNA be translated into more than one protein sequence? Can more than one type of mRNA be transcribed in a single cell? Solution The prokaryotic mRNAs are called as polycistronic since a single mRNA codes for more than one protein, whareas the eukaryotic mRNA is monocistronic, because it codes for single polypeptide.hence the given statement true for prokaryotes. Second statement is also absolutely true. Because in a cell meny genes are in the process of transcription or translation or both at the same time in the same cell.hence one cell has more than one type of mRNA..
