The correct choice that describes the structure of DNA is:
A sugar-phosphate backbone with nitrogen bases in the middle forming a double helix.
This option accurately reflects that the sugar and phosphate form the backbone of the DNA molecule, while the nitrogen bases pair in the interior, forming the rungs of the double helix structure.
