The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break-when both sides of the DNA helix are cut at once. Healthy cells can normally fix ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...
