The term polycistronic mRNA meansa. There is more than one mRNA strand produced during each round of transcription.b. There are multiple promoters to initiate transcription of this RNA.c. There are multiple operators for transcription of this RNA.d. There are multiple open reading frames in the mRNA produced.

The correct answer is option (d): There are multiple open reading frames in the mRNA produced.
Polycistronic mRNA is a type of mRNA found in prokaryotes and some viruses that contain multiple open reading frames, each encoding a different protein. During translation, ribosomes can bind at different points along the mRNA to initiate translation of each open reading frame. This allows for the efficient production of multiple proteins from a single mRNA molecule. In contrast, eukaryotic mRNAs are typically monocistronic, meaning they contain only one open reading frame and encode only one protein.
