    The lac genes are organized into an operon; that is, they are oriented in the same direction immediately adjacent on the chromosome and are co-transcribed into a single polycistronic mRNA molecule
  • Lac operon- Definition, structure, Inducers, diagram
    The lactose or lac operon of Escherichia coli is a cluster of three structural genes encoding proteins involved in lactose metabolism and the sites on the DNA involved in the regulation of the operon
  • Lac Operon - Definition, Structure, Functions, and Diagrams
    The lactose (lac) operon is a group of genes involved in lactose metabolism They are found in bacteria, most notably Escherichia coli (E coli), that use lactose as the alternate energy source when glucose is absent
