Study tracks evolutionary history of metabolic networks

By analyzing how metabolic enzymes are built and organized, researchers have reconstructed the evolutionary history of metabolism. Their study shows how metabolic networks—which drive every cellular process from protein ...

Researchers find 'protein-scaffolding' for repairing DNA damage

At the University of Copenhagen, researchers have discovered how some types of proteins stabilize damaged DNA and thereby preserve DNA function and integrity. This new finding also explains why people with inborn or acquired ...

Transforming DNA repair errors into assets

A new bioinformatics tool, MHcut, developed by researchers in Kyoto, Japan, and Montreal, Canada, reveals that a natural repair system for DNA damage, microhomology-mediated end joining, is probably far more common in humans ...
