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 ...

When we think of the structure of DNA, the image that most likely comes to mind is that of the iconic double helix. This shape was identified in 1953 as DNA's most common form, and while other ...

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 ...

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.

DNA is the genetic material used by every living organism. But, in a few edge cases, the four bases of DNA—adenine, thymidine, cytosine, and guanine—undergo chemical modifications. And in ...

Organs are complex, three-dimensional structures populated by multiple cell types. Getting a bunch of cells to form these structures is a significant challenge. One idea has been to use 3D printers.
