Its twisted, double-helix structure is one of the most iconic ... The two most important types of pentose sugar are ribose and deoxyribose, and as you can probably guess from their names, these ...

Later it was found that the sugar in nucleic acid can be ribose or deoxyribose ... Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked.

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 ...

Laying the Groundwork: Levene Investigates the Structure of DNA Meanwhile ... the first to discover the carbohydrate component of RNA (ribose); the first to discover the carbohydrate component ...

Unlike DNA, RNA is usually single-stranded. Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone to degradation. RNA is synthesized ...
