DNA Replicates, Filmed at 11.
[no description provided]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 unravelling 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. (DNA Replication Has Been Filmed For The First Time, And It's Not What We Expected," Science Alert
