The molecule most associated with the names Watson and Crick is DNA, which has ... a complicated structure, if you look at the details. But the answer the question is probably looking for is "double helix".
Watson and Crick
A double helix
James Watson,working with Francis Crick and Rosalind Franklin discovered the shape of the DNA molecule.
Watson and Crick named the shape of DNA a "double helix." This name refers to the twisted ladder-like structure of two strands of nucleotides that form the DNA molecule.
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!
James Watson and Francis Crick discovered the double helical structure of DNA in 1953. They found that the sugar-phosphate backbone lies on the outside of the molecule, while the nitrogenous bases are on the inside.
In1953 scientist Watson and crick discovered that the structure of DNA forms the shape of a double helix ladder.
Watson and Crick called the three-dimensional shape of DNA a double helix. They discovered the structure of DNA in 1953.
