For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation ...

During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a ...

Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958 ...

While scientists have long known the importance of helicase in DNA replication, "they did not know how DNA, helicases and ATP work together in a coordinated cycle to drive DNA unwinding," De ...
