base pair

n.
A pair of nitrogenous bases, consisting of a purine linked by hydrogen bonds to a pyrimidine, that connects the complementary strands of DNA or of hybrid molecules joining DNA and RNA. The base pairs are adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA.

n.
any two of the nucleotide bases that readily form weak bonds with each other, bringing together strands of DNA or RNA and linking codons with anticodons during translation of the genetic code.

base pair

The pair of nitrogen-containing bases, consisting of a purine linked by hydrogen bonds to a pyrimidine, that connects the complementary strands of a DNA molecule or of hybrid molecules joining DNA and RNA. The base pairs are adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in molecules joining DNA and RNA.
