In each species, the amount of adenine equals the amount 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.
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.
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.
Chargaff's rules state that in DNA, the amount of adenine (A) equals the amount of thymine (T), and the amount of guanine (G) equals the amount of cytosine (C). This means that A always pairs with T, and G always pairs with C in DNA.
Given that DNA base pairing rules state that cytosine pairs with guanine and adenine pairs with thymine, for every cytosine there must be one guanine. Therefore, if there are 45 cytosines, there must also be 45 guanines.
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.

Chargaff's base pair rules state that in DNA, the amount of adenine (A) is equal to thymine (T), and the amount of cytosine (C) is equal to guanine (G). This is known as complementary base pairing, where A pairs with T and C pairs with G.
Observations by Erwin Chargaff that concentrations of the four nucleotide bases differ among species. Within a species, the concentrations of adenine and thymine are always about the same and the concentrations of cytosine and guanine are always about the same. In each species, the amount of adenine equals the amount of thymine. The amount of guanine equals the amount of cytosine.
Erwin Chargaff discovered that the bases of DNA (adenine, thymine, cytosine, and guanine) attach to the deoxyribose sugars. Chargaff's rules state that in DNA, the amount of adenine always equals the amount of thymine, and the amount of cytosine always equals the amount of guanine.

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.

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
