A foldback sequence linked to a copy of the transposable element, Tam2, has been isolated, from a genomlc library constructed using partially digested and size-fractionated Antirrhinum DNA into λ EMBL4 vector, by using Tam2 specific probe. The foldback sequence visualized by heteroduplex analysis reveals a typical stem-loop structure. The foldback element is around 1.2 kb with an average of 227 bp of inverted termini forming the stem.
