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 accurately reflects that DNA has a double helix structure with the sugar-phosphate backbone on the outside and the nitrogenous bases paired in the middle.
