Transposons of higher plants (Ac/Ds or Mul of maize)
Ac and Ds are popular transposons in corn, and were earlier known to represent activator-dissociation (Ac-Ds) system. Each represents a transposon with short terminal repeats enclosing a long DNA segment, which measures more than 4500 bp in Ac and about 400bp in Ds.
Each possesses genes including the gene for transposase enzyme responsbile for transposition. Part of this region can be deleted and the transposon can be used for cloning of foreign DNA segment in much the same way as in other cases.
