Chromatin untangled: New methods map genomic structure

With some 2 meters of DNA squished into the micron-sized nucleus of every mammalian cell, to call that space “cozy” is an understatement. Yet for cells, the genome poses issues not only of compaction but of functionality: The DNA must be packaged such that it remains accessible to gene regulatory factors. Indeed, chromatin architecture plays a key role in gene regulation, but until recently, researchers had few tools with which to study that relationship… Read more at Science.
