The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical modifications of the bases, the type and concentration of metal ions, as well as the presence of polyamines in solution.The first published reports of A-DNA X-ray diffraction patterns-- and also B-DNA used analyses based on Patterson transforms that provided only a limited amount of structural information for oriented fibers of DNA..
