Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...

Brandt Eichman and Walter Chazin, professors of biochemistry, have worked together to provide a better understanding of how exactly DNA replication is initiated in eukaryotes. Using Vanderbilt's state ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

Picture in your mind a traditional “landline” telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the genetic material in ...

In turn, this slowed new DNA synthesis at replication forks, structures in which double strands of DNA separate to begin the copying process. The cells' attempt to restart the stalled replication fork ...
