The scientist that presented that deoxyribonucleic acid contained equal quantities of certain nitrogen bases is Chargaff. In addition, Chargaff’s rules state that deoxyribonucleic acid from any cell of all organisms must have a 1:1 ratio which is base pair rule of pyrimidine and purine bases and more precisely that the total of guanine is equal to cytosine and the total of adenine is equal to thymine. This configuration is found in together strands of the deoxyribonucleic acid.
