New license-free tools will allow researchers to estimate the size of DNA fragments for a fraction of the cost of currently available methods. The tools, called a DNA ladders, can gauge DNA ...

The double-stranded DNA that results from this pattern of bonding looks much like a ladder with sugar-phosphate side supports and base-pair rungs.

In our bodies, there are trillions of cells. DNA is the foundation of organisms, but what does it stand for? Get to know more about this nucleic acid.

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that make up the human genome. But where and how does the famous double helix fit into ...

There are four “letters,” or bases, in the genetic code of DNA, which pair up in a predictable way in our cells to form the rungs of the DNA ladder. It’s these strict base-pairing properties of DNA -- ...

When 28-year-old Mengqi Ji disappeared, her husband Joe Elledge was suspected of her murder. Then a hiker made a gruesome discovery, and DNA from a juniper tree sealed Elledge's fate.

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can ...

Researchers have been experimenting with DNA as a construction material since the 1980s. The first 3D shapes were simple cubes, pyramids, soccer balls -- geometric shapes with coarse and blocky ...
