What is Sleeping Beauty transposon?

The Sleeping Beauty transposon system is a synthetic DNA transposon that was constructed to introduce precisely defined DNA sequences into the chromosomes of vertebrate animals for the purposes of introducing new traits and to discover new genes and their functions.
The Sleeping Beauty transposon system is composed of a Sleeping Beauty(SB) transposase and a transposon that was designed in 1997 to insert specific sequences of DNA into genomes of vertebrate animals. DNA transposons translocate from one DNA site to another in a simple, cut-and-paste manner.
