Question

The fact that a purine base always paired through hydrogen bonds with a pyrimidine base leads to, in the DNA double helix (A) the antiparallel nature (B) the semi-conservative nature (C) uniform width throughout DNA (D) uniform length in all DNA

Since specific and different nitrogen bases occur on the two DNA chain, the latter are complementary. It is because of specific base pairing with a purine lying opposite to a pyrimidine. This makes the two chains 2 nm thick. A larger sized purine lies opposite to the smaller-sized pyrimidine, A opposite to T and C opposite to G. This gives uniform width throughout DNA.
