Chargaff's realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick's understanding of the three-dimensional, double-helical model for the structure of DNA.
Watson and Crick's discovery was also made possible by recent advances in model building (the assembly of possible three-dimensional structures based upon known molecular distances and bond angles).
Using cardboard cutouts representing the individual chemical components of the four bases and other nucleotide subunits, Watson and Crick shifted molecules around on their desktops, as though putting together a puzzle.

What kind of microscope did Watson and crick use to see the DNA molecule?
Watson and Crick used an X-ray diffraction image taken by Rosalind Franklin using a technique primarily developed by Maurice Wilkins. They did not use a microscope to directly visualize the DNA molecule.
What method did Watson and Crick use to discover the structure of DNA?
Watson and Crick used X-ray crystallography data from Rosalind Franklin and Maurice Wilkins to create a model of DNA's double helix structure. They then built physical models and made a series of deductions to propose the now-famous double helix structure of DNA.
What model did Watson and Crick use for DNA?
Watson and Crick used a double helix model to describe the structure of DNA. This model consists of two strands that twist around each other in the shape of a helix, with nucleotide bases forming pairs between the two strands.
Why did Watson and Crick succeed when Pauling failed?
Watson and Crick succeeded in determining the structure of DNA because they were able to use X-ray diffraction data from Rosalind Franklin and apply it to their model-building techniques. Pauling, on the other hand, incorrectly proposed a triple-helical structure for DNA due to the data available to him at the time. Watson and Crick's collaboration and access to critical data were key factors in their success.
What methods did Crick and Watson use to determine the structure of DNA?
Crick and Watson determined the structure of DNA using X-ray crystallography data collected by Rosalind Franklin. They also built physical models and used trial and error to discover the double helix structure of DNA, with the help of base pairing rules proposed by Erwin Chargaff.
What methoddid watson and crick use to discover DNA?
X-Ray
How did Watson Crick use Franklins x-ray to figure out the structure of DNA?
Watson and Crick used the X-ray diffraction patterns to determine that DNA was a helical molecule. Withe the use of models, they built what we know as the DNA Double-Helix.

How did rosalind Franklin help with DNA?
She didn't discovered the DNA. She contributed to the understanding of its structure. DNA was first isolated by Friedrich Miescher in 1869.

Watson and Crick used an X-ray diffraction image taken by Rosalind Franklin using a technique primarily developed by Maurice Wilkins. They did not use a microscope to directly visualize the DNA molecule.
Who is data did Watson and crick use to formulate the double helix model?
Crick and Watson have always been very open about the fact that they used Rosalind Franklin's x-ray data to deduce the double helix model of DNA.
