Quizplus · Accepted Answer

Insulators are DNA sequences that act as boundaries between different gene regulatory regions, preventing the effects of enhancers, silencers, and other regulatory elements from spreading into neighboring genes. When a transcription factor binds to an insulator, it can block the effect of a nearby silencer or enhancer, thereby modulating the expression of the adjacent genes.
