What methods did crick and Watson use to determine DNA structure?
I think it was Chargaff's Ratio, X ray crystallography and electron microscopy
How did Chargaff's rule support Watson and Crick's double helix model of DNA?
That's because of his rule, "The adenine was always connected to thymine and guanine was always connected to cytosine."
What did Watson and crick invent?
NOTHING
What molecule did James Watson and Francis Crick unravel?
DNA
Watson and crick deduced the structure of this molecule?
The molecuar 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 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.

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.
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 did Watson crick do?
James Watson and Francis Crick discovered the structure of DNA and it's significance in the transfer of information in living organisms. Hope I helped. :)
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 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.
What did Watson and Crick?
Watson and Crick discovered chromosomes
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.
How did Chargaff's rule support Watson and Crick's double helix model of DNA?
That's because of his rule, "The adenine was always connected to thymine and guanine was always connected to cytosine."
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.
