Lac Operon

Americans Jon Beckwith and James Shapiro isolated the first gene ever. The gene belonged to the Escherichia coli bacterium. The first gene itself was actually an operon – several genes transcripted from DNA into one piece of RNA. This concrete operon is called lac operon. E. coli use it to digest sugars in milk.
