DNA is the foundation of organisms, but what does it stand for? Get to know more about this nucleic acid. $3,500 iPhone possible? ... which looks like a twisted ladder.

But to teams like Reif’s and Yan’s, DNA is more than a carrier of genetic information -- it’s source code and construction material. There are four “letters,” or bases, in the genetic code of DNA, ...

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 ...

The DNA polymerase is right behind, copying the DNA letters as they’re freed from their partners. CDK’s second job is to stop any more helicases from hopping on the origins.

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 ...
