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

For almost 60 years, scientists have tried to understand why DNA doesn’t replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

If you are anything like us, whenever you plan a journey, you spend a remarkable amount of time thinking about the start and ...

The process begins by unzipping DNA's ladder-like structure, resulting in two strands called the leading and lagging strands. A molecular construction crew then assembles the missing halves of the ...

Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a discovery that could ...

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team. DNA is widely accepted to be formed of two strands that wind around one ...

Every cell in every organism on Earth copies DNA the same way. Except one bacterial protein — quietly doing something ...
