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

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 ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...

For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already ...

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed. The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...

Beef jerky and some woolly mammoths have at least one thing in common: Drying turns their DNA into super-tough glass. This glassy DNA is so stable that it preserved the three-dimensional structure of ...
