WebErwin Chargaff studied the composition of DNA and determined the following, which are known as Chargaff's rules: 1. The amount of cytosine will equal the amount of guanine in the DNA of a given species. Furthermore, the amount of adenine will equal the amount of thymine. So, C=G and A=T. 2. WebSecond parity rule. The second rule holds that both %A ~ %T and %G ~ %C are valid for each of the two DNA strands. This describes only a global feature of the base composition in a single DNA strand.
