Unformatted text preview: cytosine occur at equal rations and adenine and thymine occur at equal ratios in DNA. Watson and Crick use Chargaffs finding to include pairs of the nucleotides in the double-helix model. The base pairs are held together through hydrogen bonding with one another. o With Franklins image of the B form of DNA, Watson and Crick are able to prove the double helix structure and re-create the angles the helix makes in a model. Watson and Crick also discover that the sugar-phosphate strands that create the backbone of DNA run in opposite directions from one another to make the helix. The antiparallel model is able to explain DNA transcription. Watson and Crick receive credit for the discovery that used the data in Franklins research at Kings College. Their aim was to build the model before Linus Pauling in the United States....
