Essential physical features of the structure of B-DNA
Note in
particular the anti-parallel, 5'-3'
directionality of either strand, the alternation of phosphate and
deoxyribose sugars in either strand, the
characteristic H-bond base pairing
of CG and AT pairs between
either strand, and the presence of major
and minor grooves in the
double stranded-molecule.
