Variation in the loop regions accounts for the diversity of DNA sequences recognized by Ig-fold proteins, but there are recurring themes in the interactions made by specific loop regions and how ...

The information DNA contains is the instructions that the cell uses to make proteins. Proteins play a big part in determining the characteristics of specialised cells and whole organisms.

The findings also revealed that DNA can be repaired by cooperation between repair proteins. These proteins organize themselves into "hubs," where multiple damaged DNA regions come together.
