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 ...

If the engines of DNA replication stay in high gear all the time, they eventually stall or even break down. Fortunately, these engines, which consist of protein complexes, have what could be called ...

The repair of damage to genetic material (DNA) in the human body is carried out by highly efficient mechanisms that have not yet been fully researched. A scientific team has now discovered a ...

New work shows that physical folding of the genome to control genes located far away may have been a critical turning point for life on Earth. For evolutionary biologists, what most distinguishes the ...
