Verified
When a transcription factor binds to a(n) ____, it can block the effect of a silencer of enhancer on a neighboring gene.
A) repressor
B) insulator
C) promoter
D) operator
E) activator
Insulator
A material that resists the flow of electric charge, used in various applications to protect against electric shock or retain heat.
Transcription Factor
Regulatory protein that influences transcription by binding directly to DNA; e.g., an activator or repressor.
Enhancer
DNA sequences that increase the transcription level of a gene they are associated with, enhancing gene expression.
- Gain an understanding of the relationship between activators, enhancers, and DNA to regulate the transcription of genes.

Final Answer :
B
Explanation :
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.
