Question

Which of the following statements about transposon target-site duplications is NOT true? Group of answer choices They are organized as direct repeats in all classes of transposable elements. The length of the duplicated sequence reveals the distance between the sites attacked and cut on each strand in the target DNA. They result from the transposase-mediated strand transfer reaction. They are the recognition sequences for transposases.

Answer 1

They are the recognition sequences for transposases.

Step-by-step explanation:

Transposases are the proteins that serve to mediate the process of transposition. Bacterial simple transposons have repeated sequences at their terminals. These repeats are the sites to which the proteins transposases bind to promote the process of transposition. The target site duplication occurs to form repeats at each terminal of the bacterial transposons. These sequences are not the binding sites for transposes but are produced during the process of insertion of a transposon to the new location.
