Before revision: The extension of DNA during confinement in a nanochannel has attracted substantial attention for next-generation genomics and as a fundamental problem in polymer physics. But recent experiments measuring DNA extension in nanochannels are at odds with even the most basic predictions of current scaling arguments for the conformations of confined semiflexible polymers such as DNA.
