The positions of the genes, the enhancer, and the insulator, the transcription of gene C is most likely to be stimulated by the enhancer.
Enhancers are DNA sequences that bind to transcription factors and increase the rate of transcription of nearby genes. Insulators are DNA sequences that block the interaction of enhancers and promoters, preventing enhancers from affecting the transcription of genes beyond the insulator.
This means that the enhancer is able to interact with gene B, but not with gene D. The insulator also prevents the enhancer from interacting with genes beyond gene C.
Therefore, the most likely gene to be affected by the enhancer is gene C. Gene B is also possible, but it is less likely because it is further away from the enhancer.
Enhancers stimulate the transcription of nearby genes.
Insulators block the interaction of enhancers and promoters.
In the diagram, the enhancer is located between gene B and gene C, and the insulator is located between gene C and gene D.
Therefore, the most likely gene to be affected by the enhancer is gene C.

An Enhancer Is Surrounded By Four Genes (A, B, C, D) As Shown In The Diagram. An Insulator Lies Between Gene C And Gene D. On The Basis Of The Positions Of The Genes, The Enhancer, And The Insulator, The
An enhancer is surrounded by four genes (A, B, C, D) as shown in the diagram. An insulator lies between gene C and gene D. On the basis of the positions of the genes, the enhancer, and the insulator, the transcription of which genes is most likely to be stimulated by the enhancer? Explain.
