WebMar 1, 2024 · For example, regarding Watson and Crick’s first DNA model, a triple helix, Watson admitted: “The awkward truth became apparent that the correct DNA model must contain at least 10 times more water than was found in our model.” (Watson, 1968, p. 94) Thus, the “water content” was incorrect evidence and was coded 0.3 as “strongly ... WebJul 19, 2024 · B-form DNA. The information from the base composition of DNA, the knowledge of dinucleotide structure, and the insight that the X‑ray crystallography suggested a helical periodicity were combined by Watson and Crick in 1953 in their proposed model for a double helical structure for DNA.

WebThe Watson and Crick model also explained how specific pairings of certain types of bases and the many possible sequences of bases allowed DNA to function as genetic material. Watson and Crick based their model on X-ray diffraction images collected by Rosalind Franklin, who worked at King’s College London in London, England.
