Galactose (Gal) Operon – Structure, Regulation
What is Gal operon? The gal operon is a bacterial operon that encodes galactose-metabolizing enzymes. This operon’s gene expression is repressed by the binding of repressor molecules to two operators. These repressors form a DNA loop by dimerizing. Loop and exteRNAl operator interference prohibit RNA polymerase from attaching to the promoter, hence preventing transcription. In … Read more
