3D DNA Image (image) National Institute of Standards and Technology (NIST) Share Print E-Mail Caption JILA's new sample preparation process improves imaging of DNA in liquid, as shown in this colorized, three-dimensional view of the molecule. The gentle processing conditions yield an image of DNA at its correct length and height (680 and 2 nanometers, respectively). The method makes it possible to see the iconic double helix shape of DNA (inset). Both images were filtered to remove extraneous features.
