For the first time ever, scientists have captured a single DNA molecule replicating on video — and it’s changing the way we think about the entire process. One of the most surprising findings is how ...

Undergraduate biology students could be forgiven for thinking that scientists have DNA replication all figured out. After all, textbooks present the models of replication so matter-of-factly that it's ...

Half a century ago, scientists Jim Watson and Alexey Olovnikov independently realized that there was a problem with how our DNA gets copied. A quirk of linear DNA replication dictated that telomeres ...
