What would be the effect of moving the insulator (shown in the figure below)to a position between enhancer II and the promoter for gene B?
Homework Answers
In the above picture the Insulator acts as a barrier.
When its position moves to a position between enhancer II and the promoter for gene B, Transcription of gene B stops.
Because insulator acts as barrier between enhancer II and promoter of gene B, So enhancer does not stimulate the promoter of gene B, So trasnsctiption of gene B stops.
But the enhacer II stimulate the promotor of gene A because there is no barrier.

What control elements regulate expression of the mPGES-1 gene? The promoter of a gene includes the DNA immediately upstream of the transcription start site, but expression of the gene can also be affected by control elements. These can be thousands of base pairs upstream of the promoter, grouped in an enhancer. Because the distance and spacing of these control elements make them difficult to identify, scientists begin by deleting sections of DNA that contain possible control elements and measuring the...
