base-pairing
The specific hydrogen-bonding between purines and pyrimidines in double-stranded nucleic acids. In DNA the pairs are adenine and thymine, and guanine and cytosine, while in RNA they are adenine and uracil, and guanine and cytosine. Base-pairing leads to the formation of a DNA double helix from two complementary single strands.
