When composite transposons are formed two IS elements integrate into a chromosome with only a small distance separating them a small deletion occurs in the transposase gene of an IS element and plasmid is integrated an IS element integrates with another IS element with the help of a plasmid a small deletion occurs in the transposase gene of an IS element TRUE ANSWER : ? YOUR ANSWER : ?
