DNA: the Double Helix or the Ribbon Helix?

Authors: Lev I. Verkhovsky

The well-known difficulty of the Watson-Crick model gives the right to assume its incorrectness. An alternative model of the structure of the DNA molecule called a ribbon helix is proposed. Unlike the double helix, in it two chains are not intertwined, but go in parallel; unlike another earlier proposed structure, the so-called side-by-side model, it differs in that it has a homogeneous, dextrorotatory character. The advantages of the proposed structure are shown.
