Double helix. That is, a twin vertical spiral.
A helix
Rosalind Franklin drew a picture of a DNA molecule and it does not like similar to Watson and Crick's DNA diagram. Rosalind Franklin was smarter than them. It was used to determine the physical structure of DNA.
He and James D. Watson discovered the double-helix DNA molecule by using Rosalind Franklin's x-ray diffraction data.
Figure out the structure of the DNA molecule. Many people say the crucial input was by Rosalind Franklin, who produced the vital X-ray diffraction evidence, but she died before the prize was awarded.
she first discovered the structure of DNA.
A helix
While Crick, Wilkins and Franklin all used X-ray diffraction to try and decipher the molecule of DNA the best work was done by Rosalind Franklin with here B-51 diffraction " picture " of the double helix.
Maurice Wilkins and Rosalind Franklin
When Watson and Crick were working on the structure of DNA, they used Rosalind Franklin's discovery (she was working on X-Ray diffraction of the crystallized substance) that the molecule was helical in their work but failed to credit her contribution properly in their papers/books. Only they can answer as to why they did this, but morally it is forever to their shame.
Rosalind Franklin is known for using a technique called X-ray diffraction to study the structure of a DNA molecule. Her work was shown with or with out her permission to crick and Watson. She also worked with the BCURA on war related work. she was not JUST a chick.

X-ray diffraction
The helical nature was discovered by Rosalind Franklin and Watson and Crick first built the model of it.
Her studies of DNA with X-ray diffraction indicated that DNA is a double helix.
She was close to solve the 3D structure of the DNA molecule, she had even got the X ray diffraction pattern that was helped solve the structure by Watson and Crick.
The molecular structure of DNA was deduced by X-Ray diffractions by Rosalind Franklin. When analyzed by Watson and Crick, the DNA molecule was determined to have a double helix structure.
