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 ...
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 ...
DNA molecules are large and complex. They carry the genetic code that determines the characteristics of a living organism. The diagram shows the relationship between the cell, its nucleus, the ...
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 ...
What is it made of, and what is its function in living things? How do we study the molecular structure of DNA? And why do ...
The new finding is published in Cell in an article titled, “ SMC motor proteins extrude DNA asymmetrically and can switch directions ,” and is key to understanding how these motors shape our genome ...
Researchers have uncovered a way to manipulate DNA at the atomic level using electric field gradients to control nitrogen nuclear spins. Their findings suggest that DNA could be used as both a storage ...

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 ...
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 ...
"The length and structure of a single DNA molecule, its specific base sequence, and its interactions with proteins must be observed by stretching it for detailed analysis." ...
