"Scientists filmed DNA replication for the first time, and the results could cause a 'paradigm shift'"

"Scientists have long assumed that the DNA polymerases on the leading and lagging strands somehow coordinate with each other throughout the replication process, so that one does not get ahead of the other during the unraveling process and cause mutations.

But this new footage reveals that there's no coordination at play here at all - somehow, each strand acts independently of the other, and still results in a perfect match each time."

This is just very cool.
