Xeno nucleic acids are essential for the development of nucleic acid-based drugs. To be effective, they need to be able to stably bind to natural RNA (a cellular single-stranded version of the DNA, ...

SASKATOON -- When Francis Crick and James Watson discovered the double helical structure of deoxyribonucleic acid (DNA) in 1953, it began a genetic revolution to map, study, and sequence the building ...

The control of artificial double-helical structures, which are essential for the development of high-order molecular systems, remains difficult. In a new study, researchers have developed novel double ...

We have found that the efficiency of fluorescence resonance energy transfer between Cy3 and Cy5 terminally attached to the 5' ends of a DNA duplex is significantly affected by the relative orientation ...

The eternal molecule / Carina Dennis & Philip Campbell -- A structure for deoxyribose nucleic acid / J.D. Watson & F.H.C. Crick -- Molecular structure of deoxypentose nucleic acids / M.H.F. Wilkins, A ...

In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...

On February 28, 1953, James Watson and Francis Crick informally announced that they had discovered the double-helical structure of DNA. They soon reported their find more formally. On April 25, 1953, ...

The scientist who discovered hybridization and the "other" double helix describes what it meant to biology. By Alexander Rich Fifty-two years ago I was venturing to the basement of Cal Tech chemistry ...

James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died. He was 97. The ...
