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 ...

Every time a cell divides, its DNA is duplicated so that the two daughter cells have the same genetic material as their parent. This means that millions of times a day a biochemical wonder takes place ...

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 ...
