Given below is a schematic representation of a lac operon
Identify i and p.
(ii) Name the inducer for this operon and explain its function.
(i) i-Regulatory gene, p-Promoter gene.
(ii) Inducer is lactose.
Functions
(a) Enters the cell and binds to the repressor and inactivates it.
(b) As a result, repressor cannot bind to the operator. This allows RNA polymerase to have access to the promoter and transcription proceeds.
