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


Read this paragraph and choose the correct option from the provided answers:

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.

 Choices:

- the alkaline

- the chloride

- the protein

- the phosphate


A:
the phosphate
