Erwin Chargaff
To understand the DNA molecule better scientists were trying to make a model to understand the way it works and what it does. In the 1940 another scientist named Erwin Chargaff noticed a pattern in the amounts of the bases: adenine, guanine, cytosine, and thymine. They took samples of DNA of different cells and found that the amount of adenine was equal to the amount of thymine, and that the amount of guanine was equal to the amount of cytosine. Thus you could say: A=T, and G=C.
