What scientist first developed rules about base composition?
Chargaff
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.

How do the base pairing rule relate to chargaffs rules?
Chargaff's rule means that there should be the same number of purine and pyrimidine bases in DNA. The base pairing rules means that A always pairs with T, and G always pairs with C ie. a purine always pairs with a pyrimidine, so there must be the same number of both proving Chargaff's rule.
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.
Who discovered the base pair rules?
Erwin Chargaff
What scientist first developed rules about base composition?
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.
Explain how Chargaff rules helped Watson and Crick model Dna?
How
According to chargaff's rules the amount of guanine always equals the amount of?
cytosine
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.
Which two scientists figured out the base-pairing rules?
Ernest Chargaff (Austrian) and Waclaw Szybalski (Polish).
What do Chargaff's rules state about adenine and thymine?
In each species, the amount of adenine equals the amount of thymine.
According to chargaff's rules the percentages of what are equal to those of thymine?
adenine=thymine, cytosine=guanine
How do the base pairing rules relate to chargaffs rules?
Chargaff's rule means that there should be the same number of purine and pyrimidine bases in DNA. The base pairing rules means that A always pairs with T, and G always pairs with C ie. a purine always pairs with a pyrimidine, so there must be the same number of both proving Chargaff's rule.
