Can someone explain me lac operon in detail?
Answers
Answer:
The lac operon of E. coli contains genes involved in lactose metabolism. It's expressed only when lactose is present and glucose is absent. Two regulators turn the operon "on" and "off" in response to lactose and glucose levels: the lac repressor and catabolite activator protein (CAP).
Answer:
The lac operon (lactose operon) is an operon required for the transport and metabolism of lactose in Escherichia coli and many other enteric bacteria. ... The gene product of lacZ is β-galactosidase which cleaves lactose, a disaccharide, into glucose and galactose.
An operon is a functioning unit of genomic DNA that contains a group of genes controlled by a single promoter. ... The lac, or lactose, operon is found in E. coli and some other enteric bacteria. This operon contains genes coding for proteins in charge of transporting lactose into the cytosol and digesting it into glucose.
