DNA is found in nearly all living cells ... distances between the nucleotides that were arranged in a spiral shape called a helix. Around the same time, researchers James Watson and Francis ...

like a spiral staircase. 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 ...

"The biggest surprise was seeing the distinct spiral shape in the Hubble Space Telescope images. At first I was worried I had made an error," said Achenbach, who made the discovery during the ...

The DNA molecule was composed of the traditional sugar backbones and nucleotide pairs, but rather than the well-known right-handed spiral of the double helix structure, famously discovered by Watson ...

DNA origami is a fabrication technique wherein researchers fold DNA strands to create precisely shaped 2- and 3-dimensional nanostructures. These highly programmable structures have the potential ...

This stunning image of NGC 6951 is captured by NASA's Hubble Telescope. It is a barred spiral galaxy located in the constellation Cepheus. It is located at a distance of about 75 million light-years ...
