Research Casts New Light on 3D Structure of DNA

This image shows the structure of DNA calculated with the supercomputer simulations (in color) superimposed upon the electron cryo-tomography data (in white or yellow); one can see that the familiar double helix has been either simply bent into a circle or twisted into a figure-8.
