DNA repair has been captured in a step-by-step molecular movie
Researchers now know how a light-powered DNA repair system works Alexey Kotelnikov/Alamy Two teams of researchers have uncovered microscopic details of how a protein called photolyase uses light to repair DNA. The discovery could help develop sustainable technologies for chemical manufacture that rely on sunlight. Most organisms, except many mammals, have photolyase. These proteins repair…
