The cAMP receptor protein (CRP) is said to be responsible for positive regulation of the lac operon because (D) CRP bound to the CRP-binding site stimulates the transcription of the lac operon.
CRP is a regulatory protein. It binds to the cAMP and causes a conformational change. This allows the CRP to bind to a specific site at the promoter region of the DNA. This then activates the transcription process.
Lac operon is a group of genes that allow the uptake of glucose in bacteria. There are four components of lac operon: regulator gene, promoter gene, operator gene and structural genes. The machinery of operon is turned on the lactose itself.
