Answer:
mRNA that encodes multiple different polypeptide products
Explanation:
Polycistronic mRNA is a single molecule of mRNA that contains many genes, each one with its own start codon AUG, and therefore can be translated into many different polypeptides.
The polypeptide products usually have a related function, they can be either different subunits of a particular protein, or participate in a metabolic process.
Polycistronic mRNA is typically found in prokaryotes.
