Scientists reveal DNA-enzyme interaction with first ever real time footage

For the first time scientists have been able to film, in real time, the nanoscale interaction of an enzyme and a DNA strand from an attacking virus. Researchers from the University of Cambridge have used a revolutionary Scanning Atomic Force Microscope in Japan to produce amazing footage of a protective enzyme unravelling the DNA of a virus trying to infect a bacterial host. The research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), will improve our understanding of how enzymes interact with DNA at a nanoscale but also has marked implications for scientists studying DNA repair, and could help in the search for cancer treatments... — full story
