Overview

base pairing

The linking of the two strands of a DNA molecule by means of hydrogen bonds between the bases of the nucleotides. Adenine always pairs with thymine and cytosine with guanine. See dna.

... pair symbol : bp; any of the possible pairings between two bases in opposing strands of double‐stranded DNA or RNA molecules. Adenine forms a base pair with thymine (in DNA) or uracil (in RNA) and guanine with cytosine, hence the number of adenine residues equals the number of thymine (and/or uracil) residues while the number of guanine residues equals that of the cytosine residues. See also Chargaff's rules . —basepair vb. ; basepairing ...

...base pair a nucleic‐acid base pair that differs from the Watson‐Crick base pair. In the Hoogsteen adenine‐thymine base pair the 6‐NH 2 and N‐7 of the adenine are hydrogen bonded respectively to the 4‐O and H‐1 of the thymine. The Hoogsteen guanine‐cytosine pair requires that N‐1 of the cytosine is protonated. In this base pair the 6‐O and N‐7 of the guanine are hydrogen bonded respectively to the 4‐NH 2 and the protonated N‐1 of cytosine. In Watson‐Crick base pairs the glycosidic bond of both nucleotides has the anti conformation, but in the...

...-pair substitution a point mutation ( q.v .) in which one base-pair is replaced by another. There are two subtypes. In the case of transitions, one purine is substituted by the other or one pyrimidine by the other, and so the purine–pyrimidine axis is preserved.
