WebA nucleotide is made up of a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G) or cytosine (C). C and T bases, which have just one ring, are called pyrimidines, while A and G bases, which have two rings, are called purines.

The phosphodiester backbone of DNA and RNA consists of pairs of deoxyribose or ribose sugars linked by phosphates at the respective 3' and 5' positions. The backbone is negatively charged and hydrophilic, which allows strong interactions with water. Sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. Sugar phosphates are defined as carbohydrates to which a phosphate group is bound by an est… WebDNA and RNA Both DNA and RNA are made up of a pentose sugar, phosphate group and a base. In case of DNA the hydroxyl group from the 2' position of the ribose sugar is absent , hence the... flight chicago to denver

However, double-stranded RNA (dsRNA) can form and (moreover) a single RNA molecule can, by complementary base pairing, form intrastrand double helixes, as in tRNA. WebThe sugar-phosphate backbone, as mentioned, is an important component of DNA's double helix structure. The structure of DNA is tied to its function. The pairing of the … chemin refuge sylvestre
