Double-helix (or spiral staircase). They used x-ray diffraction data from Rosalind Franklin to determine this.
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!
Watson and Crick
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.
A double helix
In1953 scientist Watson and crick discovered that the structure of DNA forms the shape of a double helix ladder.
The discovery that DNA was a double helix structure was made by James Watson and Francis Crick in 1953. Their model of DNA's structure revolutionized biology and paved the way for further understanding of genetics and heredity.
