In nucleic acids, the sequence is:

1. phosphate-sugar-base
2. sugar-acid-phosphate
3. sugar-base-phosphate
4. base-phosphate-sugar

Correct answer: sugar-base-phosphate

Solution

In nucleic acids, each nucleotide has a sugar linked to a phosphate group and a nitrogenous base. The chain is organized with the sugar-phosphate backbone, while the base is attached to the sugar, giving the sequence sugar-base-phosphate in the nucleotide structure.
