Answer:
The correct answer is polycistronic mRNA
Explanation:
There are two types of mRNA monocistronic and polycistronic. Monocistronic mRNA is the mRNA that codes for only one protein or polypeptide because it has single cistron. It is present in eukaryotes mainly.
A polycistronic mRNA has multiple cistron and codes for two or more proteins of polypeptides. Polycistronic mRNA is mainly found in prokaryotes. Prokaryotes have polycistronic mRNA because they are simpler than eukaryotes so only one promoter and operator is enough to translate multiple genes.
