Structure of DNA. The molecular structure of DNA forms a double helix with a backbone of each strand of the helix consisting of a repeating ...sugar-phosphate-sugar-phosphate... polymer; the sugar is deoxyribose.tructure of DNA.

The shape of DNA is normally described as a double-helix, which is two strands twirled loosely around each other. The DNA molecule is shaped like an extremely long ladder twisted into a helix, similar in appearance to the shape of a spiral stairway.
