Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a discovery that could ...

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team. DNA is widely accepted to be formed of two strands that wind around one ...

Every cell in every organism on Earth copies DNA the same way. Except one bacterial protein — quietly doing something ...
