Which of the following statements concerning the structure of DNA is INCORRECT? a) The sequences of bases in the two strands are determined by noncovalent bonding between adenine and thymine or guanine and cytosine. b) The backbone of each DNA strand is a repeating deoxyribose sugar- monophosphate polymer. c) Antiparallel strands of DNA spiral around the helix axis means that both strands are running in the same direction. d) The B-DNA structure is a right-handed helix with 10 base pairs per rotation of the helix. e) The planar bases stack on top of each other, perpendicular to the helix axis.

The sequences of bases in the two strands are determined by noncovalent bonding between adenine and thymine or guanine and cytosine: This statement is correct. The bases in DNA form hydrogen bonds with their complementary bases (A-T and G-C). Show more…
