Related to base pairing: complementary base pairing
base pairingThe specific complementary hydrogen bonding of nitrogenous bases—purines and pyrimidines—in a double-stranded nucleic acid. Base pairing results in the formation of a double helix between complementary single-stranded nucleic acid; in DNA, pairing is between adenine and thymine, and between guanine and cytosine. In RNA, pairing is between adenine and uracil, and between guanine and cytosine.

base pairingMolecular biology The specific complementary hydrogen bonding of the bases–purines and pyrimidines—in a double stranded nucleic acid; BP results in formation of a double helix from 2 complementary single strands; in DNA the pairs are adenine + thymine and guanine + cytosine; in RNA, the pairs are adenine + uracil and guanine +cytosine. See Hybridization.
