WebLet’s begin with Chargaff’s rule. Chargaff’s rule states that. Rule 1: The amount of Adenine ~equals the amount of Thymine. The amount of Guanine ~equals the amount of Cytosine.

WebIn 1950, Erwin Chargaff published a paper stating that in DNA of any given species, the ratio of adenine to thymine is equal, as is the ratio of cytosine to guanine. This is known as Chargaff's ratios and it was a crucial clue that helped solve the structure of DNA. Chargaff's ratios are universal: all forms of life obey this rule.
