USC scientists find DNA replication begins when the double helix, caught in a vice of proteins, melts.

Why is DNA almost always a right-handed helix? Same with alpha helices, the building blocks of proteins. Chirality, or handedness, is everywhere in biology, but the reasons can be a mystery.

Researchers have identified a new way to measure DNA torsional stiffness -- how much resistance the helix offers when twisted -- information that can potentially shed light on how cells work.

A new paper based on long-lost documents confirms that DNA discoverer Rosalind Franklin should be credited for discovering the double helix.

The double helix, though, is not the only form in which DNA exists. For the first time ever, scientists have identified the existence of a new DNA structure that looks more like a twisted, four ...

Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred to as non-B DNA—have been implicated as regulators of cellular ...
