Nature Structural & Molecular Biology - Structure of a purine-purine wobble base pair in the decoding center of the ribosome Skip to main content Thank you for visiting nature.com.

The purine structure consists of a pyrimidine ring (positions 1 to 6) fused to an imidazole ring (positions 7 to 9). Adenine and guanine, the two most common purines in DNA and RNA, share this core ...

DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

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 ...

The structure of the DNA called the double-stranded helical structure was first described by ... There are hydrogen bonds between a large purine base (A or G) on one strand and a small ...

Guanine (G) is one of the four main nucleobases found in the nucleic acids DNA and RNA, along with along with adenine (A), cytosine (C), and thymine (T). It is a purine base, meaning it has a ...
