Which enzyme is essential for the movement of DNA transposons?
Show answer and explanation
Correct answer: Transposase
Transposase is the enzyme encoded by the transposon itself. It recognizes the inverted repeat sequences at the transposon's ends and catalyzes the cut-and-paste steps: excising the transposon from its original site and integrating it at a new location.
