The DNA molecule contains complementary nitrogen bases. There are four bases, but they pair as A-T and G-C with no cross pairing. How is this accomplished?
A)A and G are polar leaning heavily to the positive. T and C are negative. A-G and T-C repel each other and cannot pair.
B)A and G do not have their polar sites in the appropriate location to pair, and the same is true of T and C.
C)A and T have two matching but opposite polar sites. G and C have 3 polar sites. The two poles will not attract and maintain attraction for three poles.
D)There is more than one correct response.
