base pair

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.

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.
