It refers to the binding preferences between the nucleotides.
Adenine has an affinity for base pairing with thymine, while guanine base pairs with cytosine.
Uracil base pairs with adenine in Rna.
This ' base pair' bonding is actually based upon the weaker yet no less bio-specific Hydrogen Bonding system. One nucleotide base pair shares two Hydrogen bonds while the other nucleotide base pair shares three Hydrogen bonds: hence the slight changes in shapes that guarantee absolute specificity of replication and transcription.
bandz will make her dane
In insertion mutations, an extra base pair is added, and in a deletion, a base pair is taken out (omitted).
Complementary base pair
Not in DNA. In DNA the only base pairs are A-T and C-G. RNA can form non-canonical base pairings, so you might get some AC in RNA structures.
Uracil. In normal DNA it would be Thymine, but in RNA Uracil becomes the base pair for Adenine.

acid: electron pair acceptor Base: electron pair donor
Complementary base pair
The molecular weight of a DNA base pair is approximately 650 daltons.

Uracil would base pair with adenine on a RNA molecule.
Affinity - Affinity album - was created in 1970.
An acid accepts an electron pair from a base.
Uracil. In normal DNA it would be Thymine, but in RNA Uracil becomes the base pair for Adenine.
