Elisabeth Rieper at the National University of Singapore and colleagues have created a model that suggests that DNA may be held together by quantum entanglement.

They say that one line of evidence for this is that a purely classical analysis of the energy required to hold DNA together does not add up, and an entanglement model plugs the gap.

The entanglement may also have an influence on the way that information is read off a strand of DNA, and that it may be possible to exploit this experimentally.
