Every new life begins after a genetic shuffle. When organisms make eggs or sperm, maternal and paternal chromosomes pair up and swap pieces of DNA in a process called crossing over. This exchange is ...

Visualizing and quantifying DNA replication dynamics in living human cells remains challenging. Here, a new super-resolution ...

The team discovered that tiny DNA structures called Holliday junctions are not just stepping-stones on the way to crossovers, as scientists long believed. Instead, they also help stabilize a ...
