A double helix!
YAY FOR POTATOs
James Watson,working with Francis Crick and Rosalind Franklin discovered the shape of the DNA molecule.
The molecule's function and chemical and physical properties
Rosalind Franklin's Photo 51 revealed the helical structure of DNA, specifically showing the double helix shape of the molecule.
C.A molecule that has a symmetrical shape will be a nonpolar molecule.

The shape of a DNA Molecule is a Double Helix
The properties of organic compounds is determined by the shape of molecule and the positive and negative charges existing on the molecule. The factor of varying electro-negativity is also very important in determining the properties.
A molecule is considered polar if it has an uneven distribution of electrons, causing one end to be slightly positive and the other end to be slightly negative. This can be determined by looking at the molecule's shape and the electronegativity of its atoms. If there is a significant difference in electronegativity between the atoms in the molecule, it is likely to be polar.

Double-helix (or spiral staircase). They used x-ray diffraction data from Rosalind Franklin to determine this.
