What would have happened if the Watson-crick model of DNA had been inconsistent with chargaff's rule?
If the Watson-Crick model of DNA had been inconsistent with Chargaff's rule, it would have indicated a fundamental flaw in our understanding of DNA structure and function. Chargaff's rule states that the amount of adenine should be equal to the amount of thymine, and the amount of guanine should be equal to the amount of cytosine in a DNA molecule. This consistency is critical for the stability and replication of DNA.
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.
What important work helped Watson and Crick develop the model of DNA?
Rosalind Franklin's X-ray diffraction images of DNA played a crucial role in Watson and Crick's development of the DNA model. Additionally, Erwin Chargaff's research on base composition in DNA provided key insights into the pairing of nucleotides.
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.
Who proposed the base pairing rule?
Watson and Crick came up with the base-pairing rule for nucleic acids using Chargaff's rule that in DNA the percentages of adenine and thymine are equal, and the percentages of guanine and cytosine are equal. Refer to the related link below.
How did Watson and Crick's DNA structure supported Chargaff's rules?
Watson and Crick's DNA structure supported Chargaff's rules by showing that the base pairs are complementary and form specific hydrogen bonds (A with T and G with C), consistent with Chargaff's observation. This structure provided a molecular explanation for Chargaff's rule that the amount of adenine equals the amount of thymine and the amount of guanine equals the amount of cytosine in DNA.
Explain how Chargaff rules helped Watson and Crick model Dna?
Chargaff's rules stated that the amount of adenine should roughly equal thymine, and cytosine should roughly equal guanine in DNA. This helped Watson and Crick understand the base pairing rules, which were crucial in developing their double helix model of DNA.
How did chargaffs rules helped Watson and crick model?
Chargaff's rules provided key information about the base composition of DNA, which guided Watson and Crick's understanding of the structure of DNA. Specifically, Chargaff's rules stated that the amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine. This information was crucial in helping Watson and Crick establish the complementary base pairing necessary for the double helix structure of DNA.
What would have happened if the Watson-crick model of DNA had been inconsistent with chargaff's rule?
If the Watson-Crick model of DNA had been inconsistent with Chargaff's rule, it would have indicated a fundamental flaw in our understanding of DNA structure and function. Chargaff's rule states that the amount of adenine should be equal to the amount of thymine, and the amount of guanine should be equal to the amount of cytosine in a DNA molecule. This consistency is critical for the stability and replication of DNA.
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.
What was the significance of chargaff experiment?
Chargaff's experiment showed that the amount of adenine is equal to the amount of thymine, and the amount of cytosine is equal to the amount of guanine in DNA. This helped Watson and Crick in their determination of the double helix structure of DNA.
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.
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.

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.
