Molecular biologists, including the cool dudes from CSI, use gel electrophoresis to separate DNA fragments from each other in order to analyze the DNA. A team of researchers under the leadership of Vici winner Serge Lemay, has now shown for the first time how the gel influences the movement of the DNA. The researchers drove a single DNA molecule through a nanopore in order to analyze the forces on the DNA. The results of the research were published on March 29 in Nature Physics.
