DNA unwinding mechanism of a eukaryotic replicative CMG helicase

The DNA duplex is known to be split apart in a steric exclusion manner during replication, but the specific mechanism has remained unclear. Here the authors present a cryo-EM structure of a eukaryotic replicative CMG helicase on forked DNA, revealing the mechanism of DNA unwinding.
