Enhancer I can stimulate the transcription of gene A, but the insulator blocks its effect on gene B Enhancer ll can stimulate the transcription of gene B, but the insulator blocks its effect on gene A What would be the effect of moving the insulator to a position between enhancer Il and the promoter for gene B? Insulator-binding protein Promoter Transcription start site Transcription start site O O O O The newly positioned insulator prevents enhancer Il from stimulating the transcription of gene B. The newly positioned insulator allows enhancer Il to hyperactivate gene B transcription. The new positioning of the insulator prevents gene A expression. The newly positioned insulator allows enhancer I to activate gene B transcription.
