Well Im in 7th grade and from what i know (Im in honors) that they did not discover the double helix but they made a model of it. But it was actually Rosland Franklins work! Its actually pretty intresting! I hope that helped.
ADD: Watson and Crick used the work of several scientists in order to develop their model of DNA and suggest a method of replication. Watson, Crick, and Maurice Wilkins received a Nobel Prize for their work on the structure of DNA. Rosalind Franklin did not receive the Nobel Prize because she had died of cancer before the Nobel Prize was given. If she had been alive she would have more than likely shared in the Nobel Prize.

Explain how chargaff's helped watson and crick model dna?
Chargaff discovered that in DNA the percentages of adenine and thymine were the same, and the percentages of cytosine and guanine are the same. This led to the idea of base-pairing between adenine and thymine, and cytosine and guanine.
Who proposed the double helix model?
James D. Watson and Francis Crick proposed the double helix structure of DNA in 1953. It was based from an x-ray diffraction image taken by Rosalind Franklin and Raymond Gosling and information on how the bases paired, which was acquired from Erwin Chargaff. Maurice Williams belongs here as well
Who hypothesized that nitrogen bases in DNA occur in pairs?
James Watson and Francis Crick are credited with the base pairing rules and DNA structure in general. Erwin Chargaff is credited with the rules of base pairs in that the number of pyrimidines is equal to the number of purines.
What is Chargaff's Rule and how was it important for determining DNA's structure?
Erwin Chargaff discovered the comlimentary base pairing and also the amount of purines is equal to that of pyrimidines. This discovery helped Watson and Crick in proposing the double helical structure of DNA in which the two stands are held together by hydrogen bonding between the nucleotide bases as proposed by Chargaff.
Watson and Crick elucidated the structure of DNA in 1953 Their research built on and helped explain the findings of other scientists including?
X-ray diffraction studies by Rosalind Franklin and Maurice Wilkins.
Explain how Chargaff rules helped Watson and Crick model Dna?
How
What is the 3 important event that led to understanding the structure of DNA?
Three events that led to understanding the structure of DNA are: Chargaff's Rules, Franklin's Discovery, and Watson and Crick's Model.
Explain how chargaff's helped watson and crick model dna?
Chargaff discovered that in DNA the percentages of adenine and thymine were the same, and the percentages of cytosine and guanine are the same. This led to the idea of base-pairing between adenine and thymine, and cytosine and guanine.
Describe the discoveries of Erwin Chargaff Rosalind Franklin and James Watson and Francis Crick?
Chargaff has Chargaff's rule named after him. That is that the number of A=T and the number of G=C in DNA.Franklin discovered the diffraction patterns of DNA. Watson and Crick put it all together, surmising that DNA is a double helix, with about 10 nucleotide base pairs per turn, and a major gap and a minor gap. They made a wire model.
Why was chargaff not included in the noble prize?
Chargaff's work laid the foundation for the discovery of the double helix structure of DNA, but his contributions were not directly recognized when the Nobel Prize for Physiology or Medicine was awarded to Watson, Crick, and Wilkins in 1962 for their discovery. It is speculated that Chargaff's exclusion may have been due to his controversial personality and his strained relationships with other scientists in the field.
What are three important events that led understanding of the structure of DNA?
Three events that led to understanding the structure of DNA are: Chargaff's Rules, Franklin's Discovery, and Watson and Crick's Model.
In Watson's book how was Rosalind Frankiln depicted?
In Watson's book, Rosalind Franklin was depicted as a talented X-ray crystallographer who made significant contributions to the discovery of the structure of DNA. However, she was often marginalized and her contributions were not fully recognized at the time. Watson's portrayal of Franklin has been criticized for being dismissive and reinforcing gender biases in science.
What were the contributions of the study of DNA from Watson and Crick?
With the help of Rosalind Franklin, Watson and Crick built a tin model of a DNA molecule that helped scientists better understand the structure of DNA.
What evidence did Watson and Crick use to deduce the structure of DNA?
They applied the clues provided by Chargaff's rules and Franklin's X-ray diffraction studies. Using brass and wire models of the bases, sugars, and phosphate groups, Watson and Crick deduced that the structure of the DNA molecule is a double helix.
Did erwin chargaff win any nobel prizes?
No, Erwin Chargaff did not win a Nobel Prize. He was an Austrian biochemist who is best known for his research on the composition of DNA, where he discovered the base pair rules known as Chargaff's rules.
Who proposed the double helix model?
James D. Watson and Francis Crick proposed the double helix structure of DNA in 1953. It was based from an x-ray diffraction image taken by Rosalind Franklin and Raymond Gosling and information on how the bases paired, which was acquired from Erwin Chargaff. Maurice Williams belongs here as well
What was Chargaff's conclusion?
Chargaff made an observation about DNA that was very important in the determination of its structure. He noticed that the amount of adenine always equaled the amount of the thymine, and the amount of cytosine always equaled the amount of guanine. This principle is known as chargaffs rule, and it helped Watson and crick eventually realize that A paired with T and C paired with G.
