4.1 The Operon Model of Gene Regulation. An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule, which therefore encodes multiple proteins (Fig. 16.11). Such polycistronic mRNA is typically found in prokaryotes. Why are eukaryotic mRNAs not Polycistronic? Question: Why areRead More →
