People have always sought ways to preserve knowledge. Ancient humans inscribed stories on cave walls more than 40,000 years ago. With the invention of language and writing, records moved to clay ...

For decades, scientists believed that DNA strands under stress would form knots, tangling into chaotic shapes. But new research led by the University of Cambridge shows otherwise: when put under ...

A new study shows that DNA forms coils under stress, not the tangled knots that scientists expected. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

This landmark study describes the structure of the human RAD51 filament with a recombination intermediate called the displacement loop (D-loop). Using cryogenic structural, biochemical, and ...

Researchers reveal DNA strand separation demands greater mechanical force in realistic cellular environments, reshaping understanding of genetic processes and molecular interactions. Credit: Stock ...

Most biochemistry labs that study DNA isolate it within a water-based solution that allows scientists to manipulate DNA without interacting with other molecules. They also tend to use heat to separate ...
