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 ...

Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment has been the focus of a 30-year research question. New work from the Crick ...

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 ...

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 ...

In turn, this slowed new DNA synthesis at replication forks, structures in which double strands of DNA separate to begin the copying process. The cells' attempt to restart the stalled replication fork ...

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 ...
