Ultraviolet (UV) rays from sunlight can cause DNA damage that leads to skin aging and cancer. Fortunately, our bodies have a highly efficient repair system capable of swiftly identifying and repairing damaged DNA sites among approximately 3 billion base pairs. Recent research by a team at UNIST has shed new light on how this process operates at the molecular level.



Summary

Sunlight’s ultraviolet (UV) rays damage DNA, increasing the risk of skin aging and cancer. Our bodies possess a remarkable DNA repair system to combat this, efficiently locating and fixing damaged sites within our vast genome. A recent study by researchers at UNIST has provided a deeper understanding of the molecular mechanisms driving this crucial DNA repair process, potentially paving the way for enhanced strategies to protect against UV-induced damage.
