Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...

A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study by Weill Cornell Medicine researchers. The work, published Jan.

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

Knowing the structure of a complex biological system isn't nearly enough to understand how it works. It helps to know how the system moves. In that light, Rice University researchers have modelled a ...

Researchers have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than ...

BERKELEY, CA -The molecular machinery that starts the process by which a biological cell divides into two identical daughter cells apparently worked so well early on that evolution has conserved it ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
