Which of the following describes a likely model for the insertion of a simple transposon?

A characteristic host sequence is cleaved to generate staggered ends, the transposon with inverted repeat sequences at each end inserts between the staggered ends, and the staggered ends are filled in and ligated to the transposon.

A characteristic host sequence is cleaved to generate blunt ends, the transposon with inverted repeat sequences at each end inserts between the staggered ends, and the blunt ends are ligated to the transposon.

A characteristic host sequence is cleaved to generate staggered ends, the transposon with direct repeat sequences at each end inserts between the staggered ends, and the staggered ends are filled in and ligated to the transposon.

Any host sequence is cleaved to generate staggered ends of characteristic length, the transposon with inverted repeat sequences at each end inserts between the staggered ends, and the staggered ends are filled in and ligated to the transposon.
