WebAn insulated located between an enhancer and a promoter prevents the activation of that promoter. If the enhancer/silencer works on its target in a downstream manner, then an insulator located upstream of the enhancer/silencer has no effect (i.e. the insulator must be located between the enhancer/silencer and its target). WebPromoters are typically found just ahead of the gene on the DNA strand. Enhancers provide binding sites for proteins that help activate transcription. Enhancers can be found on the …
