In an article published in Molecular Cell, scientists have discovered how the three-dimensional organization of DNA in our ...

In short, DNA is a complex molecule that consists of many components ... Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three ...

In 1953, Francis Crick and James Watson described the molecular shape of DNA as a "double helix." Double-stranded DNA is composed of two linear strands that run opposite to each other, known as ...

DNA was largely accepted as the genetic molecule. Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked. In 1948, Linus Pauling discovered ...

Crick and Watson were trying to build a 3D model of the DNA molecule. But they were not the only ones working on finding its structure. They were competing with a team at King's College London ...

This structure, announced in their famous paper in the April 1953 issue of Nature, explained how the DNA molecule could replicate itself during cell division, enabling organisms to reproduce ...

DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...

“Once we understand how SMC molecular motors shape DNA, we may start asking what goes wrong in diseases like cancer and neurogenerative diseases, and importantly, how to correct it,” said Barth.

Researchers have uncovered a way to manipulate DNA at the atomic level using electric field gradients to control nitrogen ...

The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...

After one DNA molecule was trapped on the surface treated by APTES, the DNA molecule was stretched by pressure flow and immobilized. Credit: AIP Advances (2025). DOI: 10.1063/5.0223375 ...
