title: [Double helix DNA].
abstract: Various conformations of the DNA complementary helix are considered. Computer calculations of the conformational possibilities of the double helix are compared with the forms known from experiment. The frequences for fluctuational transitions from the B form into the forms of higher energy (A, Z) under physiological conditions are calculated on the basis of thermodynamical parameters for the B--A and B--Z shifts.
