A polynucleotide is a nucleic acid molecule consisting of a long chain of nucleotides. Nucleotides in a polynucleotide molecule are held together by a bond between the phosphate group of one nucleotide and the sugar of a second nucleotide, which is called a phosphodiester bond.
Ok. So phosphodiester bonds link nucleotides of the same strand. Hydrogen bond holds nucleotides that are complementary to each other (forming the double helix). The question is poorly worded. Hydrogen bonds the bases of the nucleotides, but phosphodiester bonds like phosphate group of one nucleotide to the carbon ring of the next nucleotide. Strag, Jun 11, 2011 #12
