base pairing defined in 1951 yearbase pairing - base pairing;
base pairing - Two strands of nucleic acid, RNA or DNA, can associate laterally by bonds between specific pairs of the bases contained in their nucleotides. Adenine in one strand will link (by hydrogen bonding) to thymine (in DNA) or uracil (in RNA) in the other; and guanine to cytosine. DNA usually consists of two associated complementary strands (coiled together into a helix) the arrangement of their nucleotides permitting such base pairing throughout.
