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.

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 ...

Clever DNA tricks As cells divide, they must copy all of their chromosomes only once or chaos will ensue.

Learn what an autosomal DNA test is and how it can reveal information about your ancestors, ethnicity, and medical conditions.

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 ...

Designing with DNA Software lets researchers create tiny rounded objects out of DNA: Here's why that's cool Date: December 26, 2022 Source: Duke University Summary: Marvel at the tiny nanoscale ...

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 ...

DNA ladders contain DNA fragments of varying sizes. These ladders are sometimes made from restriction enzyme digestion of plasmid DNA with a known sequence. Often, DNA molecular weight markers and ...
