Detailed explanation-1: -The transposase enzyme functions to excise the transposon sequence from the host genome and insert it into a new acceptor site.

Detailed explanation-2: -Transposases are enzymes that identify the inverse terminal repeat sequences within the DNA and proceed to bind and excise the DNA transposons in between the terminals.

Detailed explanation-3: -Transposase is a enzyme associated with the transposition. Transposition relates to the level exchange of hereditary material between living beings. The enzyme binds to the transposon, i.e. a DNA sequence which are capable for replicating and embedding copies inside the genomes.

Detailed explanation-4: -Here, we review the mechanisms of the four known types of transposition reactions catalyzed by (1) RNase H-like transposases (also known as DD(E/D) enzymes); (2) HUH single-stranded DNA transposases; (3) serine transposases; and (4) tyrosine transposases.

Detailed explanation-5: -Class II transposons Class II elements are simply segments of DNA that move from one place to another via a “cut and paste” mechanism. Most, if not all, of these elements encode an enzyme called transposase, which acts to cleave the ends of the transposon, freeing it from its initial location in the genome.
