DNA

The Double Helix is the shape of DNA. The structure formed by double-stranded molecules of nucleic acids. The double-helix model of DNA structure was first published in the journal Nature by James D. Watson and Francis Crick in 1953. The DNA double helix polymer of nucleic acids, held together by nucleotides which base pair together. In B-DNA, the most common double helical structure, the double helix is right-handed with about 10–10.5 nucleotides per turn.
