Every time a cell divides, it must accurately copy its entire genetic instruction manual. Before this process can begin, cells load their DNA-copying motor—a complex of six subunits known as the ...
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 ...
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 ...
