What did Watson and Crick figure out from looking at Rosalind Franklin's "Photo 51?" it was a triple helix it was a double helix

## Step 1<br />Rosalind Franklin's "Photo 51" was a critical piece of evidence in the discovery of the structure of DNA. The photograph, taken using X-ray crystallography, provided a snapshot of the DNA molecule in action. <br /><br />## Step 2<br />The photograph revealed a clear pattern that indicated the DNA molecule was not a single helix, but rather a double helix. This was a significant discovery as it contradicted the previously accepted model of DNA structure.<br /><br />## Step 3<br />The photograph also showed that the DNA molecule was not a triple helix, but a double helix. This was a crucial piece of evidence that led to the development of the double helix model of DNA.<br /><br />## Step 4<br />The photograph also showed that the DNA molecule was not a triple helix, but a double helix. This was a crucial piece of evidence that led to the development of the double helix model of DNA.
