Wobble base pair — A wobble base pair is a G U and I U / I A / I C pair fundamental in RNA secondary structure. Its thermodynamic stability is comparable to that of the Watson Crick base pair. Wobble base pairs are critical for the proper translation of the genetic … Wikipedia
Hoogsteen base pair — A Hoogsteen base pair is a minor variation of base pairing in nucleic acids such as the A•T pair. In this manner, two nucleobases on each strand can be held together by hydrogen bonds in the major groove. A Hoogsteen base pair applies the N7… … Wikipedia

acid-base theory — Any of several theories that give rise to alternative definitions of acids and bases. The original theory was based on Svante Arrhenius s electrolytic theory of solutions and involved the dissociation of water into hydrogen and hydroxide ions. To … Universalium
base pair — Abbreviation: bp The two separate strands of a nucleic acid double helix are held together by specific hydrogen bonding between a purine and a pyrimidine, one from each strand. The base A pairs with T in DNA (with U in RNA); while G pairs with C… … Glossary of Biotechnology
