Structure of Supercoiled DNA (1 of 2 )

Caption

The image shows the structure of the DNA calculated with the supercomputer simulations (in colour) superimposed upon the cryo-electron tomography data (in white or yellow). (There is no superimposition onto cryo-electron tomography data for the purple figure-8 shape.) You can see that the familiar double helix has been either simply bent into a circle or twisted into a figure-8.
