Exercise 12
A variant of B-form DNA has been reported to exist in the presence of Li + ions. This form, called C-DNA, is found by X-ray diffraction to have A variant of B-form DNA has been reported to exist in the presence of Li + ions. This form, called C-DNA, is found by X-ray diffraction to have   base pairs per turn. (a) How many base pairs arc contained in one repeal of this structure How many turns in one repeat  (b) Is C-DNA twisted more or less tightly than B-DNA  (c) Would high superhelix density favor or disfavor C-DNA over B-DNA base pairs per turn.
