Nature Nanotechnology - A patterned anisotropic nanofluidic sieving structure for continuous-flow separation of DNA and proteins Skip to main content Thank you for visiting nature.com.

The discovery builds upon the landmark 1953 breakthrough when Watson and Crick revealed DNA’s double-helix structure. For replication to occur, the helix must first unwind, splitting into two ...

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

This strand separation is the first step in DNA replication. This breakthrough, ... Its chemical structure contains high-energy phosphate bonds that release about 7.3 kcal/mol when broken. This energy ...
