wobble
In molecular biology, unorthodox pairing between the base at the 5′ end of an anticodon and the base that pairs with it (in the 3′-position of the codon); thus, the anticodon 3′-UCU-5′ may pair with 5′-AGA-3′ (normal or Watson-crick pairing) or with 5′-AGG-3′ (wobble). Wobble pairings can occur between the unusual base hypoxanthine and adenine, uracil, or cytosine, between uracil and guanine, and between guanine and uracil, when in the 5′-position of an anticodon.
