    The double helix describes the structure of DNA.

    Explanation:

    A self-replicating material that is present in most of the living organisms as the carrier of genetic information. Double helix refers to the structure created by double-stranded molecules of nucleic acids.

    Think of the double helix structure like a spiral ladder. The sugar and phosphate molecules would be the two sides of the ladder, while the nitrogenous bases would be the rungs. Guanine pairs with cytosine, and adenine pairs with thymine.

    Thus, the correct answer is a double helix.
