Question

In the DNA double helix, purine always paired with pyrimidine base through H-bonds, that leads to (A) The antiparallel nature (B) Uniform length in all DNA (C) Uniform width throughout DNA (D) The semiconservative nature

The bases in two strands are paired through hydrogen bond (H-bonds) forming base pairs (bp). Adenine forms two hydrogen bonds with Thymine from opposite strand and vice-versa. Similarly, Guanine is bonded with Cytosine with three H-bonds. As result, always a purine comes opposite to a pyrimidine. This generates approximately uniform distance between the two strands of the helix
