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?

1 In their 1953 publication on the DNA double helix, Watson and Crick stated: "It is probably impossible to form this structure with ribose, instead of deoxyribose." The reason: The 2' hydroxyl on ...

Later it was found that the sugar in nucleic acid can be ribose or deoxyribose ... that many proteins take the shape of an alpha helix, spiraled like a spring coil. In 1950, biochemist Erwin ...

The discovery of the double helix resulted in a Nobel Prize for ... 1.2 Molecular structure of nucleic acids: A structure for deoxyribose nucleic acid This highly readable, classic paper describes ...

The backbone of the DNA double helix consists of alternating phosphate and deoxyribose sugar molecules. Interlinking bases hold the two sides together. As A is complementary to T and C is ...
