Chargaff's discovery of the base pairing rules—specifically that the amounts of adenine (A) equal thymine (T) and cytosine (C) equal guanine (G)—provided critical insights for Watson and Crick in understanding the structure of DNA. This pairing suggested a complementary relationship between the bases, which was essential for the double helix model they proposed. Chargaff's ratios helped confirm that DNA's structure would facilitate accurate replication and information transfer, key features of genetic material. Thus, his findings were instrumental in guiding their research and supporting their groundbreaking model of DNA.
What else can I help you with?
What year did rosalind Franklin discover DNA?
Rosalind Franklin did not discover DNA. DNA was discovered long before she photographed the images via X-ray crystallography. With the help of these images, Watson and Crick were able to figure out the structure of the nucleic acid in 1953. Watson and Crick did not discover DNA either; they developed the concept of the "double helix," which was accepted as the structure of DNA.
What was the scandal for Watson and Crick?
The Watson and Crick scandal was when James Watson and Francis Crick were trying to figure out the 3 dimensional structure of DNA. They came very close to discovering it when they discovered a fellow scientist named Rosalind Franklin had the data they needed. Instead of collaborating with her, Watson and Crick broke into her lab, stole her data, quickly figured out the structure, and did not give her any credit. When they won the Nobel Prize in 1962, they mentioned many names but her name was not on the list. Later, Watson openly admitted that they stole from Rosalind Franklin.
How did rosalind Franklin's x-ray diffraction affect the work of Watson and crick?
Rosalind Franklin used x-ray crystalography to receive pictures of the DNACrick and Watson then used the photo to determine that that the structure of DNA was a double helix - hoped that help :)
How did x-ray photographs help Watson and crick determine the structure of DNA?
X-ray photographs taken by Rosalind Franklin provided key information about the structure of DNA, suggesting a helical shape with a repeating pattern. Watson and Crick used this data to build a model of the DNA molecule, leading to their discovery of the double helix structure. Franklin's work was crucial in providing the evidence necessary for Watson and Crick to propose their groundbreaking model.
Did Watson and crick use Rosalind Franklin's X Ray diffraction data to deduce the structure of DNA?
Yes, James Watson and Francis Crick utilized Rosalind Franklin's X-ray diffraction data, particularly her famous Photograph 51, to help deduce the double helix structure of DNA. Franklin's work provided critical insights into the dimensions and helical nature of DNA, which were pivotal in shaping their model. However, it is important to note that Watson and Crick did not fully acknowledge Franklin's contributions in their original publications.
How did Rosalind Franklin data help Watson and crick with their researcher?
No
Watson and Crick with the help of Rosalind Franklin developed the?
double helix
Who were the two scientist to create the first 3d model of DNA?
James Watson and Francis Crick are credited with creating the first 3D model of DNA in 1953, based on X-ray crystallography data obtained by Rosalind Franklin and Maurice Wilkins. Watson and Crick's double helix model revolutionized our understanding of DNA's structure and function.
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 scientists determined the structure of DNA?
James Watson and Francis Crick are credited with determining the structure of DNA in 1953. Their discovery of the double helix structure paved the way for understanding how genetic information is stored and transmitted.
What experiments did Watson and Crick do?
Watson and Crick did not conduct experiments of their own to discover the structure of DNA. Instead, they used existing data, particularly Franklin's X-ray diffraction images, to propose the double helix model of DNA in 1953. Their model was based on analyzing and interpreting the data with the help of Chargaff's rules.

What scientist made an accurate model of DNA?
James Watson and Francis Crick are credited with discovering the double helix structure of DNA in 1953. They used x-ray crystallography data from Rosalind Franklin and Maurice Wilkins to help construct their model.
How did X-ray diffraction help Watson and Crick determine the structure of DNA?
Using the X-ray photo Rosalind Franklin had taken, Watson and Crick were able to conclude the fact that DNA is a double helix. Franklin's photo gave them an actual look at the DNA's structure.
What two things did James Watson Crick's model eventually help explain?
Watson and Crick's model of DNA's double helix structure helped explain how genetic information is stored and replicated. The model also provided insights into how mutations can occur and lead to genetic diversity.
How did x-ray diffraction photographs help Watson and crick determine the structure of DNA?
It helped reveal the characteristic shape of a double helix
What did wilkins and franklin discover about DNA?
Wilkins and Franklin discovered the structure of DNA using X-ray diffraction studies, which showed that DNA has a helical structure with a repeating pattern. Their work provided crucial insight into the double helix structure of DNA, paving the way for Watson and Crick to propose the famous model of DNA in 1953.
