The process of DNA replication relies on the coordinated action of a ring‐shaped sliding clamp and its specialised loader complexes. Sliding clamps, typified by proliferating cell nuclear antigen ...

An elusive step in the process of human DNA replication has been observed, for the first time, by scientists. The step, which is crucial for DNA replication in humans and other forms of life, had ...

Another surprise was that the 9-1-1 clamp loader complex was observed to bind DNA in the opposite orientation from other clamp loader complexes that act on undamaged DNA during normal DNA replication.

This clamp-down mounting base for concrete-placing booms can be clamped down to a foundation or structure, provided the structure is strong enough to absorb reaction loads. When used with ...

The clamp then closes and signals to the polymerases that they can begin replicating DNA. Using high-powered cryo-electron microscopes, Li, O'Donnell and their teams revealed previously unknown facets ...

For the first time, an elusive step in the process of human DNA replication has been demystified by scientists at Penn State University. According to senior author Stephen J. Benkovic, an Evan Pugh ...
