what is the name of the sugar in dna backbone
DNA Backbone. The DNA backbone is a polymer with an alternating sugar-phosphate sequence. The deoxyribose sugars are joined at both the 3'-hydroxyl and 5'-hydroxyl groups to phosphate groups in ester links, also known as phosphodiester bonds.
Like DNA, RNA is composed of its phosphate group, five-carbon sugar (the less stable ribose), and four nitrogen-containing nucleobases: adenine, uracil (not thymine), guanine, and cytosine. RNA folding in on itself into a hairpin loop. In both molecules, the nucleobases are attached to their sugar-phosphate backbone.
DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a polynucleotide.. Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group. There are four different types of nucleotides found in DNA, differing only in the nitrogenous base. The four nucleotides are given one letter abbreviations as shorthand for the four bases.
