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
group & 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.
