Though shaped like a spiral ladder it consists of two helical polymers if it was to be unwound. On the outside of the ladder is phosphate and sugars, and in the middle are the bases associated in pairs, one base coming from one helical strand and one from the opposite helical strand.

Rosalind Franklin discovered the spiral shape of DNA.
DNA exists as a double helix.
The spiral shape of the DNA molecule is called a double helix.
DNA determines a protein's shape by determining the sequence of the amino acids in a protein.
The name of the shape of DNA is called double helix. There are two long strands of DNA connected in several points. These strands twist and look like a spiral or a spring.
