Base pair

Base pair

(Science: molecular biology) two nitrogenous bases (adenine and thymine or guanine and cytosine) held together by weak bonds.

two strands of dna are held together in the shape of a double helix by the bonds between base pairs. One of the pairs of chemical bases joined by hydrogen bonds that connect the complementary strands of a dna molecule or of an rna molecule that has two strands; the base pairs are adenine with thymine and guanine with cytosine in dna and adenine with uracil and guanine with cytosine in rna.Pertaining to the complimentary nucleotide bases, such as adenine with thymine and guanine with cytosine in [[DNA.
