explain the concept of lac operon
Answers
Answer:
The lac operon is an operon, or group of genes with a single promoter (transcribed as a single mRNA). The genes in the operon encode proteins that allow the bacteria to use lactose as an energy source.
Answer:
Lac operon or Lactose operon.
Explanation:
The lactose operon (lac operon) is an operon required for the transport and metabolism of lactose in E. coli and many other enteric bacteria. When lactose is required as a sugar source for the bacterium, the three genes of the lac operon can be expressed and their subsequent proteins are translated. It would be wasteful to produce enzymes when no lactose is available or if a preferable energy source such as glucose were available. The lac operon uses a two-part control mechanism to ensure that the cell expends energy producing the enzymes encoded by the lac operon only when necessary.
