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 ...

WE have formulated a structure for the nucleic acids which is compatible with the main features of the X-ray diagram and with the general principles of molecular structure, and which accounts ...

Sugar: In DNA, the sugar is deoxyribose, while in RNA, it is ribose.The sugar forms the backbone of the nucleic acid strand. Phosphate Group: The phosphate group is attached to the sugar and helps ...
