Thymine suffers more UV damage than uracil in lab tests, but its damage pathways could help explain its place in DNA.

Our genes evolved to fight ancient threats, but in the modern world, some of those changes may be turning against us.

A study at Texas A&M University suggests that thymine may have helped early genetic molecules survive by directing that damage into a form that was easier to reverse. The findings, published in ...
