What is an insulator? A protein that blocks RNA polymerase from interacting with a promoter A sequence of DNA that inhibits the action of enhancers in a position-dependent manner A transcriptional repressor protein that surrounds the telomeres and centromeres A special type of histone that occurs at the boundaries of genes A segment of DNA that forms supercoiled heterochromatin that is devoid of any DNA-regulator binding What is an insulator?
