Answer / sruthi
The lac operon is an operon required for the transport and
metabolism of lactose in Escherichia coli and some other
enteric bacteria. It consists of three adjacent structural
genes, a promoter, a terminator, and an operator. The lac
operon is regulated by several factors including the
availability of glucose and of lactose. Gene regulation of
the lac operon was the first genetic regulatory mechanism
to be elucidated and is often used as the canonical example
of prokaryotic gene regulation.
