The sequence of the DNA backbone is

Explanation:
DNA’s backbone is a chain of alternating sugar (deoxyribose) and phosphate groups linked by phosphodiester bonds. The sequence can be viewed from any point along the strand, since the chain is continuous; what matters is the repeating pattern of one sugar followed by one phosphate, and so on. Saying phosphate-sugar-phosphate-sugar conveys that alternating arrangement and, by starting at a phosphate, emphasizes that there is no single fixed starting unit on a continuous strand. The backbone is not a simple nucleotide chain itself, but the sugar-phosphate framework that supports the nucleotide bases.
