half the base-pairs will be A-G pairs and half will be C-T pairs.
each base will form at least two hydrogen bonds with a base in the opposite strand.
the two strands will form an antiparallel left-handed helix with 12 base pairs per turn.
there will be covalent phosphodiester bonds between the two strands.
