Watson and Crick used Franklin and Goslingâ??s â??Photo 51â?? to determine the three-dimensional shape of DNA. â??Photo 51â?? is the X-ray diffraction image of DNA that shows the pattern of DNA structure.
The double helix
Watson and Crick determined that DNA molecules are in the shape of a double helix, which resembles a twisted ladder. The double helix structure consists of two strands that are connected by complementary base pairs.
Watson and Crick's model DNA in the shape of a double helix.
Watson and Crick called the 3-dimensional shape of DNA a double helix.

A double helix
In1953 scientist Watson and crick discovered that the structure of DNA forms the shape of a double helix ladder.
Double-helix (or spiral staircase). They used x-ray diffraction data from Rosalind Franklin to determine this.
Watson and Crick called the three-dimensional shape of DNA a double helix. They discovered the structure of DNA in 1953.
