The three-dimensional structure of the genome determines how genes are expressed, new research from the Garvan Institute of Medical Research and the University of Washington has found.

For the new research, the genome’s 3D structure was analyzed in detail and at high resolution, which yielded new insight into how/why some genes are expressed and others aren’t. Some background — there’s somewhere around three meters worth of DNA tightly folded within the nucleus of every one of the human body’s cells. Depending on the ‘folding’, some genes are ‘expressed’, while others aren’t.
