Newly discovered protein prevents DNA triplication

Every time a cell divides, its DNA is duplicated so that the two daughter cells have the same genetic material as their parent. This means that, millions of times a day, a biochemical wonder takes place in the body: the copying ...

Solving a long-standing biological search problem

How the cell can mend broken DNA using another DNA copy as template has puzzled researchers for years. How is it possible to find the correct sequences in the busy interior of the cell? Researchers from Uppsala university ...
