In the absence of glucose and in the presence of lactose, the lac repressor is bound to the allolactose, and the lac operon can start.
<h3>What is the lac operon?</h3>
A lac operon is an inducible operon that is activated in the presence of lactose in the outer surroundings of the bacteria. Operon is a series of genes present in the bacterial DNA.
When the lactose is present, the repressors move to bind the allolactose, and as a result, the RNA polymerase can access the lac operon. The repressor has more affinity for allolactose than the operator. RNA polymerase, along with cAMP and CAP proteins, initiates the transcription of lac operon. The transcript has genes for galactosidase, permease, and transacetylase.
Hence, in the absence of glucose and in the presence of lactose, the lac repressor is bound to the allolactose.
