Question

What is the fundtion of the repressor in the E. coll lac operon? The epressor is a region of DNA at the start of the lac operon, where RNA potymerase binds to begin transcription of the lactose genes The repressor is a protein that prevents the transcription of the lactose genes by binding to the beginning of the lac operon The repressor is a region of ONA at the start of the lac operon that switches lactose gene expression on or of protein binding The repressor is a region of DNA outside of the lac operon, which expresses a protein hat controls the transcription of the lactose genes us careers privacy poky term, o, use contact MacBook A 0 F5 2 4

Explanation / Answer

Answer - The repressor is a protein that prevents the transcription of the lactose genes by binding to the beginning of the lac operon.

Repressor is a protein binds to the operator region of LAC operon to swith OFF the operon mechanisms. When Allo lactose binds to repressor protein it undergoes conformational changes and not able to bind operator sites and operon turned ON.
