Question

Quizplus · Accepted Answer

Polycistronic transcription units are commonly found in the genomes of both Archaea and Bacteria. These units encode multiple genes within a single mRNA molecule and are often found in operons that encode proteins with related functions. In contrast, eukaryotic genes are typically monocistronic, encoding a single protein per mRNA molecule.
