Transposases are the enzymes which catalyze transposition. They have the following characteristics to facilitate transposition of a transposon to a target site:
• Recognition and binding sites for target DNA (Deoxyribo Nucleic Acid) sequences
• Excision of transposon from the donor site by creating double strand breaks
• Insertion of transposon to the target site through their “integrase” activity
• Transposase enzyme can bind to target DNA. Thus, option (a) is true
• The enzyme catalyzes the excision of a transposable element from a donor site. Thus, option (b) is true
• The enzyme catalyzes the insertion of a transposable element into a target site. Thus, option (c) is true
• As all of the above options are true, the correct answer is option (d) all of the above
