WebSep 7, 2024 · A nucleoside and a phosphate group make up a nucleotide. The bond between the deoxyribose sugar of the nucleoside and the phosphate group is a 3'-5' phosphodiester linkage. The bases, located inside the double helix, are stacked. Stacking bases interact with each other through the Van der Waals forces. WebEach DNA strand has a backbone that consists of alternating: a) purines and pyrimidines b) nucleotide bases c) hydrogen bonds and phosphodiester linkages d) deoxyribose and phosphate e)...

WebThe phosphate group of one nucleotide bonds covalently with the sugar molecule of the next nucleotide, and so on, forming a long polymer of nucleotide monomers. The sugar–phosphate groups line up in a … WebMar 22, 2024 · Ammonia (NH3) emissions have caused a wide range of environmental problems and serious harm to human health. However, efficiently separating NH3 and simultaneously recovering high purity of NH3 easily remains a great challenge.

What are the bonds that hold together the DNA backbone called?
WebThe glycosidic bonds holding paired bases are directly across the helix from one another. Bases stack together through hydrophobic interactions and van der Waals forces. Appropriate base pairing builds a polymer whose external dimensions are not consistent. The sugar-phosphate backbones are 1. 2. 3. 4. Show transcribed image text Expert Answer WebJan 14, 2024 · The polymer consists of a sugar - phosphate - sugar - phosphate backbone, with one base attached to each sugar molecule. As with proteins, the DNA backbone is polar but also charged. It is a polyanion. The bases, analogous to the side chains of amino acids, are predominately polar. WebPhosphodiester linkages are covalent bonds between the 3′ carbon of one nucleotide and the 5′ phosphate group of another. They form by dehydration synthesis reactions (Figure 5.3). Nucleic acids have directionality: the first nucleotide in the chain has a free phosphate group at the 5′ end of the molecule. chips bags encanto
