Phosphate backbone
phosphoester linkages
weak hydrogen bonds hold together sugars and phosphates
A phosphodiester bond holds the deoxyribose sugar and phosphate group together in a DNA molecule. This bond forms between the 3' carbon of one deoxyribose and the 5' carbon of the adjacent deoxyribose in the DNA backbone.
glycosidic bonds
Covalent bonds between a sugar molecule (deoxyribose) and a phosphate group make up the backbone of DNA. These are very strong covalent bonds and are broken only with great expenditure of energy--x-rays, for example.
its a scienfic bond that consist of hyper sugars that hold nucleic acids together.
RNA molecules are held together by covalent bonds, such as phosphodiester bonds in the sugar-phosphate backbone. In addition, RNA molecules also form hydrogen bonds between complementary bases (A-U and G-C) in the double-stranded regions.
A covalent bond
The polar covalent bond between the hydrogen and oxygen atoms holds it together.
