How Do Operons Regulate Gene Expression In Prokaryotes?

by

How Do Operons Regulate Gene Expression In Prokaryotes? Prokaryotic operons are commonly controlled by the binding of repressors to operator regions, thereby preventing the transcription of the structural genes. Such operons are classified as either repressible operons or inducible operons. How do prokaryotes use operons to control genes? In prokaryotic cells, there are three types
