How do base pairing rules relate to the structure of DNA?
Well the base paring rules are the rules that state that cytosine pairs with guanine and adenine those pair with thymine in DNA, and also that adenine pairs with uracil in RNA. On the other hand, the DNA structure is the crosspieces and combinations of four chemicals called nucleotides: adenine, cytosine, thymine, and guanine. Adenine only links with thymine and cytosine only links with guanine. The structure is called a double helix, and is common to all DNA.
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.
What did Chargraffs rule state?
Basically chargoffs rule, of i all know, Thymine equals the Adenine, Cytosine equals the Guanine, and something else about the pyrmine. - nikkiYes, Nikki is close and she has the right idea. Erwin Chargraff, an American biochemist, had discovered that the percentages of guanine (G) and cytosine (C) bases are almost equal in any sample of DNA. But the same thing is true for the other nucleotides, adenine (A) and thymine (T). (A) = (T) and (G) = (C) became known as Chargraff's rules. - bradberrya
State the base-pairing rules in DNA?
Adenine binds toThymineCytosinebinds toGuanineThe shapes of the bases are specific and can only fit their complimentary base. Hydrogen bonds hold them together. In RNA Thymine is replaced by Uracil.
Whats is Chargaff's rule?
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. This pattern is found in both strands of the DNA. They were discovered by Austrian chemist Erwin Chargaff.

If a segment of DNA has 20 adenine in its base composition what percent thymine is there?
The concentration of A must be equal to the concentration of T and the concentration of G must be equal to the concentration of C. This is because of the base pair rules that state that A pairs with T and G pairs with C. If you have a gene where [A] is 20%, this means that [T] also equals 20%. This puts the total concentration of A and T at 40%. Therefore the concentration of G and C is 100-40 which is 60%. This means that the concentrations of G and C are each 30%. []=concentration

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.
What does Chargaffs rule state?
In 1949 Chargaff proposed several rules. Which are as follows;the total number of purine nucleotide(A+G) is equal to the total number of pyrimidine nucleotide(C+T),i.e.(A+G)/C+T)=1;A+G+T+C=1(in terms of molecular fraction)the amount of adenine (A) is always equal to the thymine(T):A=T or A/T=1the amount of guanine (G) is always equal to the cytosine(C):G=C or G/C=1in the bases constitute of DNA ,the number of 6-amino group is equal to the number of 6-keto groups;G+T=A+Tthe numbers (A+T) and (G+C) are the only variables .

Do the rules in the game of Scattergories state that a an etc cannot be used?
Yes. The rules state that the determiners 'a', 'an' and 'the' are not allowed.
