1 answer

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.

In DNA, the sugar and phosphate groups form the backbone, and the nitrogen bases pair in the center, leading to the characteristic double helix shape.
