Unexpected slowdowns or spikes in this signal were often interpreted as knots in DNA. But now, a new study published Aug. 12 ...

DNA doesn’t knot under stress. A new study finds it coils into plectonemes, reshaping models of genome mechanics. For decades ...

In 1957, just four years after Francis Crick and other scientists solved the riddle of DNA’s structure—the now famous double ...

DNA aptamers are powerful molecular tools in biosensing, bioimaging and therapeutics. However, a limited understanding of ...

Postmitotic myotubes cannot complete DNA replication following forced cell cycle reactivation. Comparative genomic ...

Rare form: Novel structures built from DNA emerge Date: July 20, 2015 Source: Arizona State University Summary: Scientists have worked for many years to refine the technique of DNA origami. His ...

When you think of DNA, odds are, you picture the famous double helix, a ladder-like structure elegantly twisted like a corkscrew. But DNA doesn't always assume this form. The existence of one ...

Growing evidence is implicating non‑B-form DNA structures in processes related to DNA stability and function, including replication and transcription. In particular, genomic studies are ...

In a world first, researchers have identified a new DNA structure -- called the i-motif -- inside cells. A twisted 'knot' of DNA, the i-motif has never before been directly seen inside living cells.

In 1963, Popular Science reported on the Nobel Prize-winning discovery, and Rosalind Franklin⁠—the woman who was left out of the accolades.
