This model was based on 3 strands with unionized phosphate groups in the middle holding the molecule together. This didn't make sense because if the phosphate groups still had hydrogens, DNA would not be an acid... which it is.
Watson and Crick had evidence indicating that the width of the DNA molecule suggested a double helix rather than a triple helix. Additionally, base pairing rules they proposed provided a more plausible explanation for the structure of DNA. These findings led them to conclude that the triple helix model was incorrect.
Francis Crick worked with James Watson to discover the double-helix structure of DNA. Their collaboration led to the groundbreaking 1953 paper that revolutionized the field of molecular biology.
Francis Crick, along with James Watson, is credited with the discovery of the DNA molecule. Together, they proposed the double helix structure of DNA in 1953.
James Watson and Francis Crick, along with other researchers such as Rosalind Franklin and Maurice Wilkins, are credited with discovering the double helix structure of DNA in 1953. Watson and Crick's model was based on X-ray crystallography data from Franklin and Wilkins.
Francis Crick and James Watson discovered the double helix structure of DNA in 1953. Their groundbreaking discovery revolutionized the field of genetics and paved the way for advancements in molecular biology.
Watson and Crick discovered the structure of DNA at the University of Cambridge in England in 1953.

The first correct shape was the double helix by Watson and Crick. However, there were earlier incorrect models, for example the incorrect triple helix model proposed by Linus Pauling. Even the first model by Watson and Crick turned out to be incorrect; they had it inside out compared to the correct model.
James Watson and Francis Crick
James Watson and Francis Crick discovered the structure of DNA.
The person who helped discover the shape of DNA is James Watson, along with Francis Crick.
The discovery of the structure of DNA was a culmative effort. After the discovery that the genes were paired, Watson and Crick suggested the first accurate model of DNA structure in the journal of Nature.
James Watson and Francis Crick are credited with discovering the double helix structure of DNA in 1953, based on the work of Rosalind Franklin.
