All of the following tend to favor a helical conformation of a
single polynucleotide chain EXCEPT:
A) charge–charge repulsion of phosphate residues of the
polynucleotide backbone.
B) interchange of electrons in the p orbitals of the purine
and pyrimidine bases.
C) hydrophobic interactions of the rings of the purine and
pyrimidine bases that exclude water.
D) hydrogen bonding between appropriate purine–pyrimidine
pairs.
