nucleic acid modificationpseudorotationribosesugar conformationThe modification of the ribofuranose in nucleic acids is a widespread method of manipulating the activity of nucleic acids. These alterations, however, impact the local conformation and chemical reactivity of the sugar. Changes in the ...
carryingmoleculeof thecelland that directs the process ofproteinsynthesis, thereby determining the inherited characteristics of every living thing. Nucleic acids are further defined by their ability to be broken down to yieldphosphoric acid,sugars, and a mixture of organic bases (purinesandpyrimidines...

The pKa values for many nucleic acid–base derivatives have been measured potentiometrically and provide one measure of the propensity of a site to bind metals. The pKa values in Figure 1 are for the nucleosides, the derivatives with sugars attached at the purine N9 and pyrimidine N1 positions...
Biological Polymers: macromolecules formed from the joining together of small organic molecules. Carbohydrates: include saccharides or sugars and their derivatives. Proteins: macromolecules formed from amino acid monomers. Lipids: organic compounds that include fats, phospholipids, steroids, and waxes....
The assumption that d-ribose would be the common sugar in all nucleic acids soon became problematic, as the chemical properties of the sugars in each of the two acids proved to be markedly different. Specifically, whereas yeast nucleic acid (RNA) would readily degrade when heated with ammonia,...

Nucleotides contain what kind of sugars? A) three-carbon B) four-carbon C) five-carbon D) six-carbon E) seven-carbon Name the monomer of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base...
The other type of nucleic acid, RNA, is mostly involved in protein synthesis. The DNA molecules never leave the nucleus but instead use an intermediary to communicate with the rest of the cell. This intermediary is the messenger RNA (mRNA). Other types of RNA—like rRNA, tRNA, and micro...
