Polycistronic mRNA:

Polycistronic mRNA may be defined as the mRNA that has the ability to code multiple proteins from a single mRNA molecule. This type of mRNA is generally found in prokaryotes.

Operon:

Operon may be defined as the DNA functional unit that contains the cluster of genes. These gene are regulated by the single promoter. These operon system are generally found in prokaryotes.

Regulon:

Regulon may be defined as the group of genes that acts as a single regulatory unit. The protein expressed by regulon can acts as a activator or repressor. These are generally found in eukaryotes.
