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 ...

Nucleic acid is essential for all forms of life, and it is found in all cells. ... The 5-carbon sugar (known as a pentose) includes ribose and deoxyribose, which are present in nucleic acid.

DNA (Deoxyribose Nucleic Acid) is the coding molecule that allows human cells to replicate and function. Human DNA is organised into compact structures called chromosomes of which humans have 23 pairs ...

"We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A). This structure has novel features which are of considerable biological interest." With this famous understatement ...

The central dogma or the directional flow of genetic information from a deoxyribose nucleic acid (DNA) template to a ribose nucleic acid (RNA) transcript, and finally into a functional protein, is ...

Less than a year before Watson and Crick’s paper, "A Structure for Deoxyribose Nucleic Acid," was published in Nature, 60 years ago today, Rosalind Franklin sent around a hand-lettered obituary: ...
