  • Lac Operon
  • The lac operon (lactose operon) is an operon required for the transport and metabolism of lactose in Escherichia coli and many other enteric bacteria. Although glucose is the preferred carbon source for most bacteria, the lac operon allows for the effective digestion of lactose when glucose is not available through the activity of beta …

  • Transcription
  • For a bacteria to express the genes on the lac operon they are first transcribed by RNA polymerase. The regulation of the expression of most genes is done at the level of transcription. The transcribed mRNA is then translated into proteins by ribosomes. Response to Lactose. E. coli express a protein called the lac repressor.

  • Operon
  • Today, the operon is simply defined as a cluster of genes transcribed into a single mRNA molecule. Nevertheless, the development of the concept is considered a landmark event in the history of molecular biology. The first operon to be described was the lac operon in E. coli.

  • Operon
  • In the absence of lactose, the repressor protein encoded by the I gene binds to the lac operator and prevents transcription. Binding of allolactose to the repressor causes it to leave the operator. This enables RNA polymerase to transcribe the three genes of the operon. The single mRNA molecule that results is then translated into the three …

  • Lac Operon. 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 regulation of the operon. Many protein-coding genes in bacteria are clustered together in operons which serve as transcriptional units that are coordinately regulated.
