Why is DNA said to be antiparallel?
a) Each strand of the double helix is made up of a sugar phosphate backbone
which runs in the 5' to 3' direction.
b) DNA has polarity such that one strand runs in the 3' to 5' direction and the
other in the 5' to 3' direction.
c) The two strands of DNA are joined together via complementary base pairing
such that AT run in the 3'to 5' direction and CG run in the 5' to 3' direction.
d) The DNA strands twist into a helix conformation once the bases have joined
to form major and minor grooves.
