I want to know the answer to the following question:
How do regulatory regions on different chromosomes operate in order to allow regions on different chromosomes to come into contact with one another?
All the background I'm provided with is that "Regulatory regions of a gene such as enhancers do not necessarily have to be close to the coding sequence on the linear molecule because the intervening DNA can be looped out to bring the gene and its regulatory region into proximity.". Is that enough to answer the question?
