Rosalind Franklin. After discovering the existence of the A and B forms of DNA, Rosalind Franklin also succeeded in developing an ingenious and laborious method to separate the two forms, providing the first DNA crystals pure enough to yield interpretable diffraction patterns. She then went on to obtain excellent X-ray diffraction patterns of crystalline B-form DNA and, using a combination of crystallographic theory and chemical reasoning, discovered important basic facts about its structure. She discovered that the sugar-phosphate backbone of DNA lies on the outside of the molecule, not the inside as was previously thought. She discovered the helical structure of DNA has two strands, not three as proposed in competing theories. She gave quantitative details about the shape and size of the double helix. The all- important missing piece of the puzzle, that she could not discover from her data, was how the bases paired on the inside of the helix, and thus the secret of heredity itself. That discovery remained for Watson and Crick to make. Rosalind Franklin.

Watson created a model of the DNA double helix structure along with Francis Crick. Rosalind Franklin discovered the structure of DNA by using X-ray diffraction. Watson and Crick used Franklin's unpublished data without her consent in the construction of the double helix model and took credit for the findings.
Watson - American scientist crick - british physicist and biologist developed the double helix/DNA structure. along with Franklin and wilkins.
James D Watson and Frances Crick used data from X-ray crystallography obtained formally by Rosalind Franklin, to work out the double-spiral structure of a DNA molecule. They achieved this in 1953 and were awarded, along with Maurice Wilkins awarded a Nobel Prize in 1962.
James Watson and Francis Crick discovered the structure of DNA in 1953. Watson and Crick, along with Maurice Wilkins shared the Nobel Prize in Physiology or Medicine in 1962. The prize was for their discovery regarding the molecular structure of nucleic acids and its importance in the information transfer in living material.
Francis Crick
Francis Crick (along with James Watson) co-discovered the double-helix model of the DNA structure.

James D. Watson wrote the book "The Double Helix," which describes the discovery of the structure of DNA. Watson, along with Francis Crick and Maurice Wilkins, was awarded the Nobel Prize in Physiology or Medicine in 1962 for this groundbreaking work.
Francis Crick
James Watson is famous for discovering DNA along side with Francis Crick. hope this helps x
Watson and Crick using Rosalind Franklin's x-ray of a double helix of DNA which she had not yet realized was a double helix Rosalind Franklin made an x-ray that showed the nucleotide structure of DNA. Watson and Crick used her x-ray to make their 3-D model of DNA's structure.
Francis Crick is co-discoverer of the double helix structure of DNA, along with James Watson. He played a pivotal role in research related to sequencing the genetic code.
