A double helix
Helix
Watson and Crick called the three-dimensional shape of DNA a double helix. They discovered the structure of DNA in 1953.
It's called a "double helix".
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.
Biomolecular structure is the intricate folded, three-dimensional shape that is formed by a molecule of protein, DNA, or RNA, and that is important to its function.

The three-dimensional shape of the DNA molecule is a double helix, which resembles a twisted ladder. This structure allows the molecule to have stability and store genetic information. The double helix is made up of two strands of nucleotides that are connected by hydrogen bonds.
Watson and Crick determined the three-dimensional shape of DNA through model-building and analysis of X-ray diffraction images captured by Rosalind Franklin. Their model of the double helix structure of DNA was based on the complementary base pairing of adenine-thymine and guanine-cytosine, as well as the sugar-phosphate backbone.
The DNA molecule has a double helix structure, meaning it is twisted like a spiral staircase. The DNA molecule consists of two strands that are linked together by chemical bases, forming a shape that resembles a twisted ladder. This three-dimensional shape allows DNA to compactly store genetic information in the cell.
