Men who studied and aanlyized Dna based on the data of Chargaff and Franklin. They both together discovered and than made a model of what they thought to of been the true struture of DNA. The strutcure is listed as follows 1.two outside strands are made of deoxyribo and phosphate.2.cytosine,guistine pair by three hydrgoen bonds.3.thymine and adenine pair by two hydrogen bonds.
