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 ...

To better understand BKPyV replication and ways to prevent it, researchers in the UAB Department of Microbiology have published a single-cell analysis of BKPyV infection in primary kidney cells. Their ...

Scientists uncovered DNA's double helix structure in 1953. James Watson and Francis Crick proposed the model. It explained ...

It's tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate everything inside of them, including their neatly packaged DNA, then split in half.
