Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...

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 ...

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 ...

An elegant collaboration between researchers in the UK's two core-funded Medical Research Council Research Institutes, the Laboratory of Medical Sciences (LMS) in London and the Laboratory of ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...

Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, ...
