Answer:
The CRA-cAMP complex increases the rate of expression of lac operon when glucose is absent and lactose is present as nutrient.
Explanation:
CRP is the catabolite gene activator protein that forms a complex with cAMP. The CRP-cAMP complex facilitates the binding of RNA polymerase to the promoter region of the lac operon. This robust binding as stimulated by CRP-cAMP complex is followed by the formation of open complex and initiation of gene expression.
Hence, the CRP-cAMP complex positively regulates the lac operon and increases its expression when glucose is not present.
