Webmolecule. [1] In polymer science, the polymer chain or simply backbone of a polymer is the main chain of a polymer. Polymers are often classified according to the elements in the main chains. The character of the backbone, i.e. its flexibility, determines the properties of the polymer (such as the glass transition temperature). 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 …
WebThese strong bonds form a sugar-phosphate backbone. The ends of the DNA strand are called the 5' end (said as "5 prime end") at the phosphate end, and the 3' end at the deoxyribose end. WebThe chemical backbones of the double helix are made up of sugar and phosphate molecules that are connected by chemical bonds, known as sugar-phosphate backbones.
WebSep 28, 2024 · Upon condensation, the nucleotides that form the phosphodiester would now have a sugar-phosphate backbone, which is a structure necessary for nucleic acid structural stability and function. WebOct 7, 2024 · Regardless of whether the nucleic acid is DNA or RNA, the basic formula is the same. Take a nitrogenous base, add on a 5-carbon sugar with a phosphorous group, and bind together.

The sugar-phosphate backbone has multiplex electronic structure and the electron delocalisation complicates its theoretical description. Some part of the electronic density is delocalised over the whole backbone and the extent of the delocalisation is affected by backbone conformation due to hyper-conjugation effects. Hyper-conjugation arises from donor-acceptor interactions of localised orbitals in 1,3 positions. the tin forest book pagesWebDescribe nucleic acids' structure and define the two types of nucleic acids; Explain DNA's structure and role; ... The sugar and phosphate lie on the outside of the helix, forming the DNA's backbone. The nitrogenous bases are stacked in the interior, like a pair of staircase steps. ... The phosphate backbone is located on the outside, and the ... setting up a test azure tenantWebDNA consists of a pair of chains of a sugar-phosphate backbone linked by pyrimidine and purine bases to form adouble helix ( Fig. 96.1). The sugar in DNA is deoxyribose. The pyrimidines are cytosine (C) and thymine (T); the purines are guanine (G) and adenine (A). The bases are linked by hydrogen bonds such that A always pairs with T and G with C. setting up a telecasterWebribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds … the tin forest book imagesWeb9.
