Secondary structures of DNA.
In view of the differences of the X-ray diffraction patterns for DNA fibers at 66 and 92 per cent relative humidities, it is proposed that the secondary structure of DNA consists of two partially intercalated double helices at 92 per cent. Possible biological implications are discussed.
