DNA,our genetic fabric, normally has the structure of a twisted rope ladder. Experts call this structure a double helix. Among other things, and it is stabilized by stacking forces between base pairs. Scientists at the Technical University of Munich (TUM) have succeeded at measuring these forces for the very first time on the level of single base pairs. This new knowledge could wait on to construct precise molecular machines out of DNA. The researchers published their findings in the journal Science.
