Applying the Goldilocks principle to DNA structure: Scientists consider the form that may be 'just right' for scripting gene expression

Inspired by ideas from the physics of phase transitions and polymer physics, researchers set out to determine the organization of DNA inside the nucleus of a living cell. Their findings suggest that the phase state of the genomic DNA is 'just right' -- a gel poised at the phase boundary between gel and sol, the solid-liquid phase transition.
