The bond linking a phosphate group to a sugar of a another molecule is called a phosphodiester bond.
The five carbon sugar(deoxyribose) attached to the phosphate group is joined to one another to â¦ form the sides of the DNA, forming a covalent bond of sugar-phosphate-sugar-phosphate etc. Also, one of 4 nitrogen bases of DNA are attached to the sugar, which is in turn attached to each other.The purines(double ringed base) which are A and G bond with the pyrimidines T and C respectively. The bonding between the two creates a hydrogen bond.lso, one of 4 nitrogen bases of DNA are attached to the sugar, which is in turn attached to each other. The purines(double ringed base) which are A and G bond with the pyrimidines T and C respectively.
