Using cryo-electron microscopy, which enables visualization of frozen molecular structures at high resolution, the team analyzed this unique complex at a resolution of 3.66 Å (less than a ...

The determination in 1953 of the structure of deoxyribonucleic acid (DNA), with its two entwined helices and paired organic bases, was a tour de force in X-ray crystallography. But more ...

Figure 1: The chemical structure of a nucleotide. A single nucleotide is made up of three components: a nitrogen-containing base, a five-carbon sugar, and a phosphate group.
