where do sugars pucker in dna
Thus, the sugar phosphate backbone was shortened, producing a double helix in which the base pairs were slightly displaced from the center of the helix to produce a flatter and somewhat wider helix. Air-dried fibers were used to produce the A-type diffraction pattern. The A conformation was stabilized by the smaller number of water molecules compared to the B conformation. It soon became clear that the normal conformation in the hydrated in vivo environment involved the C2' endo sugar pucker of B-form DNA.
