For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...

Deoxyribonucleic acid (DNA) replication is fundamental to life, yet the precise mechanics of how helicases unwind the genome for replication remain unclear. A recent study published in Nature used ...

DNA helicases unwind DNA by a number of mechanisms in which conformational change seems to be of central importance. Characterization of two β-hairpins and fluorescence resonance energy transfer ...
