Chargaff's rule is adenine ALWAYS goes with thymine
guanine ALWAYS goes with cytosine

What scientist first developed rules about base composition?
Erwin Chargaff, an Austrian biochemist, first developed rules about base composition in DNA in the early 1950s. Chargaff's rules stated that the amount of adenine is roughly equal to thymine, and the amount of guanine is roughly equal to cytosine in DNA molecules.
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 chargaff arrive at his rule?
Erwin Chargaff arrived at his rule in the late 1940s after conducting research on the composition of DNA. His findings, known as Chargaff's rules, highlighted the complementary base pairing in DNA, such as the equal ratios of adenine to thymine and guanine to cytosine.
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.
When did Chargaff discover DNA?
He didnt discover DNA, Erwin Chargaff proposed two main rules in his lifetime which were appropriately named Chargaff's rules. The first and best known achievement was to show that in natural DNA the number of guanine units equals the number of cytosine units and the number of adenine units equals the number of thymine units. The second of Chargaff's rules is that the composition of DNA varies from one species to another, in particular in the relative amounts of A, G, T, and C bases. Such evidence of molecular diversity, which had been presumed absent from DNA, made DNA a more credible candidate for the genetic material than protein.
Who discovered the base pair rules?
Erwin Chargaff

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.
How are the base pairing rules related to Chargaff on DNA?
Chargaff's rules state that DNA from any cell of all organisms should have a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine.
Who discovered the amount of adenine in DNA is always equal the amount of thymine?
Erwin Chargaff discovered the rule that the amount of adenine in DNA is always equal to the amount of thymine. This finding was a key breakthrough in understanding the base pairing rules in DNA.
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.

Who is chargraff?
Erwin Chargaff was a biochemist known for his discovery of the base pairing rules in DNA. Chargaff's rules state that the amount of adenine is equal to thymine and the amount of guanine is equal to cytosine in a DNA molecule. These rules were integral to the development of the double helix model of DNA by Watson and Crick.
What Chargaff's rules is correct?
Chargaff's rules state that in a DNA molecule, the amount of adenine is equal to thymine and the amount of cytosine is equal to guanine. This is known as base pairing: A pairs with T and C pairs with G. This rule is crucial for understanding the structure and function of DNA.
According to chargaff's rules the percentages of what are equal to those of thymine?
According to Chargaff's rules, the percentage of adenine is equal to thymine in a double-stranded DNA molecule. These rules state that in DNA, the amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine.
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.
Which two scientists figured out the base-pairing rules?
Ernest Chargaff (Austrian) and Waclaw Szybalski (Polish).
