Historical
Members of the Tn3 family were among the earliest transposons to be identified. In fact, the word “transposon” was used for the first time in 1974 by Hedges and Jacob in a seminal article in which they showed that ampicillin resistance could be transmitted between a number of different plasmids [1]:
“We designate DNA sequences with transposition potential as transposons (units of transposition) and the transposon marked by the ampicillin resistance gene(s) as transposon A “.
