Zooming in on Enzyme that Repairs DNA damage from UV rays

UV light creates damaging links between atoms in the DNA building block thymine. An enzyme called photolyase, which is triggered by a different wavelength of light, cuts them out and repairs the damage. Credit: Colored illustration by Dave Goodsell/PDB-101
