Answer the following question given this paragraph: 

The sugar of one nucleotide binds to the phosphate group of the next nucleotide. Alternating sugars and phosphate groups form the backbone of a nucleotide chain, as shown in Figure below . The bases, which are bound to the sugars, protrude from the backbone of the chain. In DNA, pairs of bases-one from each of two nucleotides-form the middle section of the molecule.


Q: The sugar of one nucleotide binds to what group of the next nucleotide?


A:
the phosphate
