Which of the following is not true about the cut-and-paste pathway of transposition?
A. The reaction forms covalent intermediates as did recombinases of site-specific recombination.
B. At the target site, the insertion sites on each strand are staggered to create short repeated sequences at each end of the inserted transposon.
C. Cut-and-paste transposition leaves double-stranded breaks at the donor site that can be repaired by recombination repair.
D. The transposases molecules bound to either end of the transposon come together before cutting at the 3' ends of the transposon.
E. The 3' ends generated by transposase now attack the 5' ends of the transposon, forming hairpins at the ends of the transposon as it is released from the DNA.
