Molecular sunscreen: How DNA protects itself from UV light

22 junio 2015

Using X-rays, scientists measured the ultrafast response of DNA nucleobases to UV light. They found that the UV excited state in the nucleobase thymine decays rapidly, harmlessly dissipating the potentially destructive UV energy. The findings give new insight on how the nucleobases inside DNA protect themselves from light-induced damage.
