Biologists discover how to make long distance work
Long-range enhancer-promoter contacts work like power lines, connecting regions of the genome which are very far away from each other. Image from pixnio.com under CC PDM 1.0. Enhancers are non-coding elements which are littered throughout the mammalian genome. Enhancers form three-dimensional physical contacts with gene promoters, the sequence immediately upstream (before) the gene’s protein/RNA coding…
