Angus · Answer 1

target site direct repeats.

Explanation:

This type of cut and paste transposition is known as conservative transposition and non-replicative mode of transposition. This means that transposon is completely removed from its original sequence and moved to the other (target site) via enzymes tranposases.

The gaps formed by the action of transposases are being filled in by DNA polymerase. Upon excision, direct repeats are left in the chromosomal DNA.
