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.

What this exact temperature is depends on the length of the DNA molecules (longer chains of nucleotides have more bases and thus more potential H-bonds) and also the sequence; as mentioned above an A:T base pair has two H-bonds while a G:C base pair has three, so sequences with more "G:C content" stick together more strongly than sequences with more A:T base pairs.
