| James Watson and Francis Crick are the first people to make a model of DNA. They revealed DNA's true form. This helped explain how Dna was copied and how it controlled the cell. The model matched with Chargraff's and Franklin's discoveries |

| Edwin Chargraff founs that the Adenine is always equal to thymine. Same with Guanine and Cytosine. i.e, 20% A=20% T=30% C= 30% G |
