The correct answer 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 represents the classic double helix structure of DNA, where the sugar-phosphate backbone forms the sides of the helix and the nitrogen bases pair in the interior.
