DNA has an oscillating double-helix structure. This oscillating means that the DNA molecules conduct electricity much less well than was previously thought. Ultrafast cameras were one of the devices the researchers from Amsterdam used to demonstrate this.
It turns out the DNA does not have a rigid regular structure as stated in textbooks. In reality the double helix of DNA forms a very dynamic chaotic system. The rigid structure in textbooks should be regarded as the average position of many structures taken over a period of time.
The Amsterdam researchers showed that the chaotic movements limit the electrical conductivity properties of DNA. Electrical conductivity, even if it is imperfect, is of vital importance for the cell. For example, the cell uses electrons from the charge transfer in DNA to repair damaged bonds.
