base pairing

The specific complementary hydrogen bonding of nitrogenous bases—purines and pyrimidines—in a double-stranded nucleic acid. Base pairing results in the formation of a double helix between complementary single-stranded nucleic acid; in DNA, pairing is between adenine and thymine, and between guanine and cytosine. In RNA, pairing is between adenine and uracil, and between guanine and cytosine.

base pairing

Molecular biology The specific complementary hydrogen bonding of the bases–purines and pyrimidines—in a double stranded nucleic acid; BP results in formation of a double helix from 2 complementary single strands; in DNA the pairs are adenine + thymine and guanine + cytosine; in RNA, the pairs are adenine + uracil and guanine +cytosine. See Hybridization.

base pairing

hydrogen bonding between NUCLEOTIDE bases of DNA. See COMPLEMENTARY PAIRING.
