Which statements explain the primary difference between the structure of a nucleic acid and the structure of a protein?
A nucleic acid has alternating base pairs. A protein has alternating peptides
Nitrogen bases form the backbone of a nucleic acid.. Peptides form the backbone of a protein
Nucleotides link together to form a nucleic acid. Amino acid link together to form a protein
