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.
When did erwin chargaff discover the base pairing rule?
Erwin Chargaff discovered the base pairing rule in the late 1940s while studying the ratios of nucleotides in DNA from various species. This finding was a key contribution to understanding the structure of DNA and laid the foundation for Watson and Crick's model of the DNA double helix.
Chargaff showed that DNA contains equal amounts of cytosine and?
guanine, and equal amounts of adenine and thymine. This became known as Chargaff's Rule, a crucial discovery in understanding the structure and function of DNA.
What did chargaff show?
Chargaff's work revealed that in DNA, the amount of adenine always equals that of thymine, and the amount of guanine always equals that of cytosine. This discovery contributed to the understanding of DNA structure and laid the foundation for Watson and Crick's model of the DNA double helix.
Who discovered the nitrogenous bases of DNA please need this quick.?
Erwin Chargaff is credited with discovering the nitrogenous bases of DNA and establishing the base pairing rules (Chargaff's rules) that helped lead to the discovery of the double-helix structure of DNA by Watson and Crick.

Who is erwin chargoff?
Erwin Chargaff was an Austrian biochemist who emigrated to the United States during the Nazi era and was a Professor of biochemistry at Columbia University medical school. Through careful experimentation, Chargaff discovered two rules that helped lead to the discovery of the double helix structure of DNA.
What contribution did Francis Crick make to the discover of the structure of DNA?
they described the structure of DNA
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.
Who discovered that the percent of bases in DNA varies from organism to organism?
Erwin Chargaff discovered that the percentage of adenine (A) is equal to thymine (T) and the percentage of guanine (G) is equal to cytosine (C) in DNA. This discovery is known as Chargaff's rules and laid the foundation for understanding the structure of DNA.
What did chargaff show?
Chargaff's work revealed that in DNA, the amount of adenine always equals that of thymine, and the amount of guanine always equals that of cytosine. This discovery contributed to the understanding of DNA structure and laid the foundation for Watson and Crick's model of the DNA double helix.
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.
Who is Chargaff?
Erwin Chargaff was born in Austria-Hungary on August 11, 1905 and died in New York City on June 20, 2002. He was a biochemistry professor at Columbia University. Chargaff is credited with discovering information that led to the discovery of the double helix structure of DNA.
Who discovered the nitrogenous bases of DNA please need this quick.?
Erwin Chargaff is credited with discovering the nitrogenous bases of DNA and establishing the base pairing rules (Chargaff's rules) that helped lead to the discovery of the double-helix structure of DNA by Watson and Crick.
The work of Chargaff Wilkins and Franklin formed the basis for?
The work of Chargaff, Wilkins, and Franklin formed the basis for the discovery of the double-helix structure of DNA by Watson and Crick in 1953. Their research on the chemical composition and x-ray diffraction patterns of DNA provided crucial insights that helped in deciphering the structure of the DNA molecule.
