Which of the following statements is true with respect to the DNA double helix?

Which of the following statements is true with respect to the DNA double helix? Correct Answer The base pairs have opposite polarity

The two strands having complementary base pairing have the same helical geometry but have opposite polarity. This is because the strands are held together are antiparallel in nature.
