Before your very eyes

A recent paper in Cell has uncovered somewhat unexpected aspects of the DNA replication process — like the fact that the DNA polymerase on each strand of DNA does not actually collaborate. The two polymerases work independently, stopping and starting as they copy the existing strands. Perhaps this shouldn’t come as a surprise, given that we know a lot of processes depend on random factors like when two molecules happen to collide. But nonetheless, one of the authors of the paper calls it “a paradigm shift” in how we think about DNA replication.

You can read the paper in Cell here, but there’s also a short video available on Youtube which you can see for yourself! You can find that here.
